Vitus Sentier 29 VRS Mountain Bike - Oryx Grey - Red - XL, Oryx Grey - Red
  • £1119.99
  • RRP £1599.99
  • Saving you £30

Vitus Sentier 29 VRS Mountain BikeThe Sentier 29 VRS is an award-winning hardtail mountain bike (MTB) that is strong, lightweight and it looks great. It rolls upon 29" wheels and is equipped it with 130mm-travel Fox 34 Float Rhythm suspension forks that soak-up bumps and knocks from the terrain and offers exceptional traction in all riding conditions. It is also armed with a Shimano Deore 1x12-Speed groupset, a 10-51 Tooth wide-range cassette and Shimano hydraulic disc brakes. And it rolls upon WTB i30 TCS 2.0 Tubeless Ready wheels wrapped in Schwalbe SnakeSkin Addix Compound tyres.Fast, Agile and Stylish Hardtail Mountain BikeThe Vitus Sentier VRS mountain bike has quickly established itself as a classic hardtail, having amassed something of a cult following thanks to its confident and playful character. But it’s not just the people’s champion, the Sentier is a multi-award winner that continues to prove itself out there on tough trails and All Mountain adventures. A hardtail that won’t shy away from technical descents and aggressive riding, it never fails to find that flow and excite. Snappy, obedient and nimble, like a hardtail should be, yet also hungry to go all-in where things get steep and challenging. Where other hardtails get weak at the knees.Let’s be clear. The Sentier is not all cheeky upstart and bluster. Far from it. From head to toe, this bike is dressed to impress to deliver the finest trail riding experience. The longer, slacker geometry gives it the control and stability to cruise the tricky sections, while the shorter stem keeps the handling precise should you need to whip it through the turns.From the dropper post to the 1x12 speed Deore drivetrain and the 130mm Fox Float fork, this mountain bike casually exudes performance. The double-butted aluminium frame and quality components are ready to go straight from the box, but as you get to know your Sentier, as you become addicted to its personality, so this becomes the perfect chassis to put your own stamp on. To personalise and customise your dream hardtail setup.For full-day sessions with mates. For cruising the climbs and railing the descents. For balance and poise with no loss of entertainment. For keeping the fun-factor turned right up. Any time on-board the Sentier is playtime.Features: Frame: Sentier Aluminium 6061-T6 Double Butted, IS disc brake mounts, BSA threaded BB, Boost hub spacing - 148mm x 12mm thru axle Fork: Fox 34 Float Rhythm Series 29”, 130mm travel, GRIP damper, Float air spring, 34mm stanchions, , tapered alloy steerer, Boost hub spacing - 110mm x 15mm bolt through axle Headset: Acros AZX-212-CO R5, ZS44/28.6 upper & ZS56/28.6 lower to suit 1-1/8" upper tapered to 1.5" lower headtube Handlebar: Nukeproof Neutron V2 Riser, 6061 Alloy, 25mm Rise, 9° Back Sweep, 31.8mm Clamp Diameter, S & M: 760mm Wide, L: 780mm Wide, XL: 800mm Wide Stem: Vitus 50mm Reach, Alloy, 31.8mm Handlebar Clamp Diameter, 3° Rise Grip(Tape): Vitus Lock On, N/A Wheelset: WTB i30 TCS 2.0 rims on Vitus KT hubs, 29" Wheelset, 32H, 6 Bolt, Boost 110mm x 15mm Front & 148mm x 12mm Rear Hub Spacing Front Rim: WTB i30 TCS 2.0, 29", 32H, Presta Valve, Tubeless Ready Rim Tape Installed Rear Rim: WTB i30 TCS 2.0, 29", 3H, Presta Valve, Tubeless Ready Rim Tape Installed Front Hub: Vitus KT DHF112, 32H, 6 Bolt Disc Fitment, 110mm x 15mm Rear Hub: Vitus KT H5ER-SH, 32H, 6 Bolt Disc Fitment, 148mm x 12mm Front Tyre: Schwalbe Magic Mary, 29", 2.4", Evo, Super Trail, TLE, Addix Soft Rear Tyre: Schwalbe Hans Dampf, 29", 2.3", Performance, DD, RaceGuard, TLE, Addix SpeedGrip Spoke: Stainless Steel, Double Butted Chain: Shimano Deore M6100, 12 Speed, 114 Links Crankset: Shimano Deore M5111 or Race Face Ride, 12 Speed, 32T Narrow Wide Chainring, 170mm Crank Length Bottom Bracket: Shimano BB52 or Nukeproof, BSA Threaded BB, 73mm Shell F/brake Set: Shimano MT520 or SRAM DB8 - Post Mount, Four Piston Calipers R/brake Set: Shimano MT520 or SRAM DB8 - Post Mount, Four Piston Calipers Brake Rotors: Shimano RT56 or SRAM CenterLine - Post Mount, Four Piston Caliper Front Derailleur: N/A, N/A Rear Derailleur: Shimano SLX M7100, 12 Speed, Shadow Plus, Long Cage Left Shifter: N/A, N/A Right Shifter: Shimano Deore M6100, 12 Speed, Rapidfire Plus Freewheel: Shimano Deore M6100, 12 Speed, 10-51T Range Saddle: Nukeproof Neutron or Vitus Saddle, Black, Steel Rails Seat Post: Brand-X Ascend Dropper, Remote lever, 31.6mm Diameter, S: 100mm drop, M: 125mm drop, L & XL: 150mm drop Seat Screw: Vitus, 34.9mm Diameter Weight: Medium: 13.1kg (tubeless setup)Please note that due to ongoing issues in the global bike supply chain, manufacturers may substitute certain component items due to availability.

  • Saving you £16

Campagnolo Levante 2-Way Fit Carbon Gravel WheelsetFeaturing a high-quality carbon fibre rim construction with a variety of performance-enhancing technologies, Campagnolo's first all-gravel wheelset makes its debut. Famous for its craftmanship on road and track wheels, Campagnolo has applied its expertise to the gravel market. The Levante wheelset is reactive, versatile and durable they are made for Point and Shoot handling. Levante, is named after the Easterly wind of the Mediterranean and brings a host of proven Campagnolo technologies to the gravel scene.Gravel Wheelset with Handmade Ultra-Light Carbon RimsStiff for climbing, light for handling and compliant for descending, Levante benefits from Campagnolo's Handmade Ultra-Light Carbon (H.U.L.C) which is used in the rim construction and is the result of extensive development over decades of in-house carbon fibre moulding. This enables Campagnolo's engineers to optimise the usage of both fibre and bonding resin for the perfect blend of strength, stiffness and lightweight. All of this combines to create an awe-inspiring ride feel without undue harshness and a wheelset that weighs in at just 1485g.The Levante rim sports the beautiful mirror-like finish aptly named Campagnolo Luxury (C-LUX). This finish is so pristinely smooth that it doesn't require any additional lacquer, saving valuable grams across the wheelset. The Levante pairs this stunning finish with durable laser-etched rim graphics capable of withstanding even the most demanding of gravel rides.Campagnolo's consideration for durability is deeply rooted in the Levante Wheelset, and the premium H.U.L.C construction combined with an asymmetric offset on the rim provides a strong and balanced wheel that can take the rough with the smooth. A simple cup and cone hub system meanwhile ensures ease of servicing and external nipples allow for tool-free on-the-go spoke tensioning if needed.Two-Way Fit Technology for Tubeless and ClincherNot only is the Levante wheelset durable but it's versatile too. Campagnolo's two-way fit rim profile ensures tubeless and clincher compatibility while the 25mm internal rim width can accommodate 38mm to 78mm tyres (1.5-3.0”).The wheelset's Mini-Hook has been designed specifically for the Levante rim and matches the E.T.R.T.O Clincher and Tubeless requirements using the most minimal dimension possible. As a result, the slight hook provides a perfect match between the tyre and rim. This means a large contact area with the terrain, increasing grip and comfort at lower pressures.Campagnolo's Next 3 Ways (N3W) option is compatible with Campagnolo 11, 12 and 13-speed cassettes. The wheelset is also available with freehub bodies for Shimano HG and SRAM XDR (please choose the option from the menu).

  • Saving you £40

Nukeproof Reactor 290 Alloy Frame - GreyBoasting a rock-solid 6061 aluminium build, this trail-ready mountain bike (MTB) frame is engineered to endure the most demanding of terrain conditions. Thanks to its hydroforming and triple-butting process, it offers extra durability as you charge from trail to trail. Keeping your ride smooth, its RockShox Super Deluxe Ultimate RCT rear shock also gives you increased tuneability and control for superior rear end suspension performance. This makes it perfect for blasting across rock gardens, tree roots and whatever the trail has to throw at you. Coming complete with updated geometry, internal cable routing and 148x12mm rear hub spacing, this full-suspension MTB frame is fully equipped for the demands of modern trail riding.From concept through to design, the Kinematics, the geometry and specification; the Reactor is designed from the ground up to be the ultimate aggressive trail bike. It is at home on technical climbs, but happiest when thrashing the most technical trails you can point it at.Full Suspension Alloy MTB FrameThe Alloy Reactor features a custom triple butted hydro-formed tube set and carbon seat stays, which help reduce the overall weight of the frameset. Critically this reduces the unsprung weight; making the suspension as active as possible.The Reactor is available for 27.5” or 29” wheel sizes. These are two totally different, compromise free frames that were designed and developed at the same time. Each frame is simply tailored around each wheel size.Speed or play: which do you value more? The manoeuvrability of 27.5” or the raw speed of a 29”?Adjustable GeometryAll Reactor frames feature a “flip chip” to adjust the geometry from “Trail” to “Rail mode”.Trail - As the name suggests, this setting is best suited for trail riding. It is for riders who get as much enjoyment from the climb as the descents.Rail - The Rail setting turns the Reactor into a corner shredder, dropping the bottom bracket 6mm and slackening the head angle by half a degree. It is there to maximise the descending capabilities.Suspension DesignTo ensure the bike could climb as well as it descends, we designed the four bar horst linkage to have higher levels of anti-squat for climbing gears but lower levels when you drop down the cassette. This means that the bike can behave itself on the climbs but when you get it up to speed, it turns into a trail hooligan. The combination of low anti-squat and progressive rate give ultimate small bump compliance (removes rough trail and root chatter) with good mid stroke support for cornering/pumping and end stroke progression for aggressive riding. Balanced anti-rise figures allow the Reactor some squat when braking hard, maintaining rider position and providing a good amount of pressure through the tyre to ensure traction. The Reactor is designed to reward the rider and ensure you get that stoke factor in on any ride.Features: Material: Nukeproof Reactor 290 Alloy, 130mm Travel, custom triple butted hydro-formed tube set for front triangle and chain stays, UD woven Carbon Fibre seat stays Use: Mountain Bike (MTB) frame Shock: RockShox Super Deluxe Ultimate RCT, Custom ML 320 tune, 210x50mm, Bearing End, 1x bottomless token fitted Fork Travel: 150mm Axle to Crown: 564mm Fork Offset: 44mm Rear Travel: 130mm Wheels Size: 29" Max Tyre Size: 2.6" Recommended Shock Sag (Measured seated): 30% Shock Size: 210x50mm Shock Hardware F: 25x8mm Shock Hardware R: 30x8mm Sizing Options: M/L/XL Headtube: 44-56mm Tapered Semi-Integrated Headset: ZS44-28.6 - T2 / ZS56/40 - B8 Bearings Required: 2x (6902 2RS), 4x (6800 2RS), 4x (6901 2RS) Seatpost: 31.6mm (Internal Routing for Dropper Seatpost) Seat Clamp: 34.9mm Bottom Bracket: Threaded 73mm BSA Rear Hub: Boost 148x12mm Rear Axle: SRAM Maxle Stealth M12x1.75 180mm (Thread Length 20mm) Chain Guide: ISCG05 Brake Mount: 180mm Direct Post Protection: 3D Contoured Rubber Frame Protection for DT/SS/CS Cable Routing: Internal cable routing ISCG05 mount Enduro bearings Weight: 3.72Kgs/8.2lbs (Medium option)Buy Nukeproof Frames & Forks from Chain Reaction Cycles, the World's Largest Online Bike Store.

The combination of low anti-squat and progressive rate give ultimate small bump compliance (removes rough trail and root chatter) with good mid stroke support for cornering/pumping and end stroke progression for aggressive riding. Balanced anti-rise figures allow the Reactor some squat when braking hard, maintaining rider position and providing a good amount of pressure through the tyre to ensure traction. The Reactor is designed to reward the rider and ensure you get that stoke factor in on any ride.Features: Material: Nukeproof Reactor 290 Alloy, 130mm Travel, custom triple butted hydro-formed tube set for front triangle and chain stays, UD woven Carbon Fibre seat stays Use: Mountain Bike (MTB) frame Shock: RockShox Super Deluxe Ultimate RCT, Custom ML 320 tune, 210x50mm, Bearing End, 1x bottomless token fitted Fork Travel: 150mm Axle to Crown: 564mm Fork Offset: 44mm Rear Travel: 130mm Wheels Size: 29" Max Tyre Size: 2.6" Recommended Shock Sag (Measured seated): 30% Shock Size: 210x50mm Shock Hardware F: 25x8mm Shock Hardware R: 30x8mm Sizing Options: M/L/XL Headtube: 44-56mm Tapered Semi-Integrated Headset: ZS44-28.6 - T2 / ZS56/40 - B8 Bearings Required: 2x (6902 2RS), 4x (6800 2RS), 4x (6901 2RS) Seatpost: 31.6mm (Internal Routing for Dropper Seatpost) Seat Clamp: 34.9mm Bottom Bracket: Threaded 73mm BSA Rear Hub: Boost 148x12mm Rear Axle: SRAM Maxle Stealth M12x1.75 180mm (Thread Length 20mm) Chain Guide: ISCG05 Brake Mount: 180mm Direct Post Protection: 3D Contoured Rubber Frame Protection for DT/SS/CS Cable Routing: Internal cable routing ISCG05 mount Enduro bearings Weight: 3.72Kgs/8.2lbs (Medium option)Buy Nukeproof Frames & Forks from Chain Reaction Cycles, the World's Largest Online Bike Store.

Campagnolo Bora One Cult 50 Disc Brake Tubular WheelsetThis tubular wheelset features two full carbon fibre rims for unequalled performance and reliability as you clock up the miles on your road bike. Boasting a 50mm high rim profile combined with Rim Dynamic Balance (RDB) exclusive technology, this model delivers perfect balance even at high speeds. Another highlight is its CULT bearings that are nine times better performing than a standard solution, guaranteeing long-lasting smoothness on every mile. Campagnolo has also kitted out this version with 6-bolt disc brake compatibility, so you will enjoy powerful and consistent braking performance, wherever your ride takes you. Coming complete with aerodynamic spokes with anodised self-locking nipples that eliminate spoke rotation, this wheelset is a perfect choice of upgrade for smoother, lighter and more reliable rolling performance for your road bike.Carbon Fibre Wheelset with CULT BearingsThe Bora One 50 Disc brake is the perfect answer for cyclists searching for deep profiles capable of offering significant aerodynamic advantages while remaining lightweight and reactive for the steepest climbs. Its extremely sophisticated carbon fibre 24.2mm rim offers a rim and tyre interface optimised for the use of both 25 and 28mm tyres, by creating a more aerodynamic complete unit and a more efficient and sure-footed structure.CULT Bearings (Ceramic Ultimate Level Technology) is a combination of the highest quality ceramic ball bearings and stainless-steel races available on the market, to reduce friction to the very minimum yet maintain a consistently high level of performance for long periods of time.The Mega-G3 Spoke pattern is a type of spoke assembly that improves energy transfer between the hub, which reduces stress on the right-hand side which in turn increases the rigidity of the wheel. This is achieved by having twice as many spokes as the left-hand side.6-Bolt Disc Brake CompatibilityThe Bora One 50 Disc represents the same quality, performance and reliability that made its rim-brake predecessor such an iconic wheel. While it incorporates any technologies used in the rim brake version, this wheelset has been specifically designed for the unique demands that come with disc brake construction. The wheel has been engineered to optimise the distribution of forces caused by disc brakes.The Bora One 50 Disc Brake Wheel is entirely hand built by a specialised Campagnolo technician and is checked in every tiny detail with electronic tools.

Once combined, these fibres are braided to obtain a “sock” of fibres then moulded. The benefits of this technology compared to other processes are an advanced ride quality, comfort and outstanding handling.  AKTIV: TIME has revolutionised the cycling world when they launched the AKTIV fork onto the market. They placed an AKTIV mass damper system in each sleeve of the fork. This lessens the vibratory phenomenon at its source and as close to the road as possible. By vibrating themselves at a given frequency, they dissipate vibrations felt in the seat, stem and handlebars. Unlike most existing systems, AKTIV fork is an active device fully preserving your physical potential, improving the behaviour of your bike, and increasing your pedalling efficiency.  Resin Transfer Moulding (RTM): RTM technology enables precise and excellent reproducibility of the desired ride characteristics. The injection of the resin under pressure ensures consistent impregnation of the fibre weave layers and eliminates the risk of delamination and structural weakness.Buy Time Frames & Forks from Chain Reaction Cycles, the World's Largest Online Bike Store.

Fulcrum Wind 75 Carbon Road Disc WheelsetThis race-ready wheelset features a high, ultra-aero profile that's ideal for time trials, triathlons and all situations where aerodynamics make the difference when pedalling at high speeds on your road bike. Fulcrum has equipped it with a high-quality full carbon rim construction with unidirectional carbon fibre finishing, so riders can enjoy the best balance of stiffness, strength and low weight performance on their ride. Aerodynamically researched and wind tunnel tested by the brand's engineers for maximum results, its rim width is 27mm and the channel width is 19mm which puts its internal and external dimension in line with modern racing trends.Full Carbon Wheelset with 2-Way Fit TechnologyFulcrum has kitted out this wheelset with a 2-Way Fit profile, which allows riders to fit both a tubeless tyre or a classic clincher. The advantages are indisputable, as the brand's tests have highlighted a unique increase in smoothness and it doesn't need any tape for sealing, simplifying and lightening the tyre-rim pairing. Because there is no tube, the friction caused by rubbing against the tyre is eliminated, while the perfect adherence of the tyre to the rim prevents the dispersion of energy. This also means that you'll have more flexibility to choose and test out which tyre works best for you. Tubeless advantages include the ability to run lower pressures for increased grip, comfort and fewer chances of flats or punctures.AFS Disc Brake Compatible and Aero Mo-Mag TechnologyReady for modern racing, this versatile wheelset is equipped with renowned Fulcrum technologies for getting the best performance out of every situation. Its AFS disc brake compatibility ensures that braking is powerful, precise and consistent, so you can tackle whatever the terrain or course conditions throw at you. Another highlight is its Mo-Mag technology that uses no holes on the rim to ensure that the rim is uniform at every point, free from stress points or zones of weakness and, for the clincher profiles no rim tape is required, for greater weight reduction.Double-Butted Spokes with Sealed Cartridge BearingsThis model's spokes are double-butted, rounded and straight-pull for excellent aerodynamic performance and the nipples are aluminium. As far as the internals are concerned, Fulcrum chose sealed cartridge bearings housed in aluminium hubs, for both the front and rear wheel.

Fulcrum has developed 2-Way Fit technology to ensure perfect compatibility of its tubeless rims with normal clincher types and tubes. 2-Way Fit road bike wheels are perfectly multipurpose for tackling every situation. Thanks to a special impression in the valve area, the tubes are fitted with maximum precision, while keeping the tube perfectly stable inside the tyre. Housing the valve for tubeless tyres is also risk-free, with the unquestionable advantage that there are never any air infiltrations caused by non-ideal positioning when fitting. AFS Axle System: The Axial Fixing System is the solution developed by Fulcrum to fix the disc brake to the hub. The constraint granted by the butt area of the release mechanism, greater than in familiar standard ones, makes it possible to obtain greater structural rigidity and therefore more precise and powerful braking. Full Carbon Rim: Full carbon Fulcrum rims are built using combinations, developed in the laboratory, of different types of fibre, including unidirectional (UD). To build them Fulcrum developed a special HTG (high transition grade) resin, whose glass transition point is at a higher temperature than any other fibre used in the bicycle industry. This gives incomparable performance when braking. Fulcrum carbon products are also recognisable for their sophisticated workmanship: The rims are moulded with ready-made nipple holes, so no further hole-making is needed. Nor is polishing necessary to give them an impeccable appearance or make them technically ready for mounting. MoMag: A magnet and lots of ingenuity. This was what led to the patent for the well-tested “Mounting Magnet” system, or MoMag. No holes on the rim mean that the rim is uniform at every point, free from stress points or zones of weakness and, for the clincher profiles no rim tape is required, to the benefit of weight reduction. The advantages are immediately clear: greater rim lifetime, greater resistance to fatigue, the possibility to give the spokes greater tension, and greater stiffness which, in terms of performance, mean greater reactivity and acceleration.Manufacturer's Part Numbers: FULC0146827 Black 700c Shimano FULC0146829 Black 700c SRAM XDBuy Fulcrum Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.

Fox Suspension 38 Float Factory Grip 2 ForkSpecifically designed for enduro riders who want to go big, this Factory Series suspension fork comes feature-packed to exceed the demands of Factory-level riders. Ready for fast enduro rides with a design that's built for speed, this model's genuine Kashima coating on its upper tubes makes it slippery smooth and ultra-durable as you conquer the most demanding of trail conditions. Thanks to its Boost axle spacing, it provides stronger and stiffer performance, while its Float EVOL air spring and GRIP2 damper with dual Variable Valve Control (VVC) make it easy to tweak it to match your riding style. Packing the same revolutionary features as the 36 model while redefining what you think a long travel single crown fork is capable of, this enduro fork sets a new benchmark for confidence, performance, and durability. Welcome to the big time.Enduro Fork with GRIP2 DamperFox Suspension's GRIP2 damper is the benchmark for unparalleled ride quality and ultra-precise adjustability. GRIP2 includes the brand's patented Variable Valve Control (VVC) technology which allows for external fine-tuning of suspension performance. GRIP2 achieves with the twist of a knob what typically requires the time-consuming and complicated task of completely disassembling and reassembling the fork.Float EVOL Air SpringEVOL technology increases negative air spring volume, optimizing small bump sensitivity. EVOL's linear spring curve delivers plushness off the top, extra mid-stroke support, and more tuneable bottom-out progression. The benefits of EVOL are further enhanced by Fox Suspension's Lower Leg channels and Bleeders, which both function to reduce air pressure captured in the lower legs, allowing the EVOL air spring to operate freely without unintended interference.Features: Upper Tubes Finish: Genuine Kashima Coat Use: Enduro, Mountain Bike (MTB) Axle Size: 15QRx110mm Boost Air Spring: Float EVOL Damper: GRIP2 damper with dual Variable Valve Control (VVC) Steerer Diameter: 1.5" tapered (internally elliptical) Compatible Rotor Size: 180mm direct Post Mount, up to 230mm compatible Weight: 2180gTechnologies: Factory Series: “Factory” says it all - feature-packed and designed to exceed the demands of Factory-level riders. What we sell is what they race. Factory Series products feature slippery smooth, ultra-durable Genuine Kashima Coat. Adjustments: High-speed compression (with VVC) 8 clicks. Low-speed compression 16 clicks. High-speed rebound (with VVC) 8 clicks. Low-speed rebound 16 clicks. Floating Axle: Floating axles might look similar to other axles, but in fact they offer a distinct performance advantage due to their unique ability to match the exact width of the fork's wheel mounting surface precisely to the front hub flange spacing, thus creating perfect chassis alignment and eliminating unwanted friction between the upper and lower fork legs. Floating axles provide much smoother suspension movement throughout the entire range of the fork's travel, notably improving sensitivity and overall ride quality. The all-new 36 and 38 come equipped with a new quick-release lever operated patent-pending floating axle system, combining the benefit of a floating axle with the ease of a tool-free quick-release. With this system, spacing is locked in via a floating sleeve, allowing repeated front wheel removal and reinstallation while maintaining perfect fork alignment. Floating sleeve positioning comes preset from the factory so if you are unsure of how to operate the floating axle system or simply don't want to bother with it, you can just install the front wheel and get on with your ride. Lower Leg Bypass Channels: As a fork compresses, the air volume within the lower legs decreases, increasing air pressure. The more the fork compresses, the more pressure increases. This effect can have the unintended consequence of preventing full travel from being achieved. Fox Suspension's lower leg channels help alleviate this issue by dramatically increasing air volume within the lower legs and thereby reducing the amount of additional unintended pressure ramping. Another benefit of these channels is that lower leg bath oil is circulated to the upper reaches of the lower legs, continuously lubricating the foam rings and bushings as the fork compresses and extends through its travel. Bleeders: Fox Suspension's lower leg bleeders allow for atmospheric pressure equalization at the simple press of a button. Pressure build-up in the lower legs dramatically decreases fork performance, preventing full travel from being achieved, and diminishing small bump sensitivity and responsiveness. Lower Leg Arch: Stiffness-to-weight is the ultimate metric for bicycle design. Engineers invest countless hours poring over every ounce of material in an effort to optimize this critical ratio. Fox Suspension's all-new lower leg design pulls out all the stops, shaving every possible gram while making sure not to compromise stiffness or strength requirements of modern enduro and gravity style riding. Modern frame designs and geometry trends require modern suspension design solutions. The arch design of the all-new 36, 38, and 40 is designed to pair perfectly with modern Enduro and Downhill bikes. Head tube profiles have grown larger and larger, and fork offsets shorter and shorter. Fox Suspension's new arch shape takes this need into account by jutting forward to provide ample headtube clearance at full compression. State-of-the-art computer modeling techniques helped us to create an organic lower leg shape that optimizes stiffness with the absolute minimal amount of material. Elliptical Steerer: The 38's elliptical steer tube is one of many ways Fox Suspension has further optimized stiffness-to-weight, placing more material only where it is needed, and eliminating every ounce of it where it's not.Manufacturer's Part Numbers: 910-21-031 Black 27.5" QR110 170mm 44mm 910-21-028 Black 27.5" QR110 180mm 44mm 910-21-027 Black 27.5" QR110 180mm 37mm 910-20-201 Orange 27.5" QR110 170mm 44mm 910-21-025 Black 29" QR110 160mm 51mm 910-21-020 Black 29" QR110 180mm 44mm 910-21-024 Black 29" QR110 160mm 44mm 910-21-022 Black 29" QR110 170mm 44mm 910-20-200 Orange 29" QR110 170mm 44mmBuy Fox Suspension Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

  • Saving you £10

Mavic Cosmic SL 65 Road Disc WheelsetPerfect for flat road races or windy triathlon events, this wheelset is kitted out with an updated Mavic rim shape that boasts a lighter overall weight as well as easier to use Road Tubeless technology. Its 100% carbon fibre rim construction means that it's strong and stiff when climbing, without any unnecessary grams holding you back as you descend. The reduced inertia of the lightweight rim delivers instant acceleration, while its lighter spokes make the wheelset feel snappier. Its 65mm deep and 26mm wide NACA rim profile also delivers low drag and stability in crosswinds, so you can get the best out of every ride.Wind-Tunnel Tested Carbon WheelsetThe wide, rounded shape of the Cosmic SL 65 rim was developed through countless hours in the wind-tunnel to produce the lowest possible drag without sacrificing stability in crosswinds. Updated and refined spokes make it 80g lighter than its predecessor, the Comete Pro Carbon UST Disc. With a revised rim bed shape, this model is easier than ever to fit tubeless or tube-type tyres. Mavic's new Infinity hub platform optimises the spoke lacing for efficient power transfer through highly controlled spoke tension. And the Instant Drive 360 freewheel coupled with automatic bearing preload (QRM Auto) provides fast engagement, high stiffness and extra durability.Centre-Lock Disc-Brake ReadyThese wheels are engineered specifically for disc brakes, with an optimised spoke count and lacing.
