Giro Imperial Road Shoes - White - EU 48}, White
  • £279.99
  • RRP £399.99
  • Saving you £30

◌Giro Imperial Road ShoesProfessional performance meets all-day comfort and unrivalled ventilation, placing the Giro Imperial Road Shoes on the top step of the podium when racing and training. Lightweight shoes are all very well but they can often lack the support needed for a stable pedalling platform, leading to loss of efficiency. Giro has tackled this by combining their highly innovative One-piece Synchwire upper with the impressively stiff Easton EC90 SLX2 high-modulus carbon sole unit, providing a supportive shoe with optimal power transfer and remarkably low weight.Synchwire UpperThe proprietary Synchwire upper construction is what provides the foot support and stability needed for efficient pedalling. A combination of an ultralight monofilament mesh, reinforced with thermal-welded Teijin TPU lets Giro strip out the weight, boost ventilation and yet still maintain durability where you need it and a supportive hold across the whole foot. This design hits the sweet spot between low weight, support for fluid pedalling and a high degree of breathability for those hot days on the bike when even the tarmac begins to melt. Precision BOA IP1 AdjustmentA secure and comfortable fit is achieved via the double BOA IP1 dials. On the fly adjustment is incredibly quick and easy, a twist of the dial offering up 1mm of micro-adjustment per click. With the Boa chord running in reinforced webbing runners you'll enjoy a smooth closure and a snug fit that eliminates hot spots and pinch points.EC90 SLX2 High-Modulus Carbon SoleThen comes the heart of any performance cycling shoe - the outsole. Here you'll find Giro's high-modulus Easton EC90 SLX2, delivering perfect stiffness-to-weight so you enjoy optimal power transfer to the pedals and minimal flex. While it's not the lightest sole unit Giro make it has the durability to stand up to your daily training and hard riding weekend races. Inside the shoe, the adjustable Super Natural Fit footbed system provides optimal pedalling efficiency with customizable arch support for performance and luxurious comfortThe result of this blend of light and airy upper, Boa fit system and stiff but durable carbon sole is a race-ready shoe which provides the perfect pedalling platform for smooth power transfer and maximum pedalling efficiency. From one hour criterium to your very own Grand Tour ride the Imperial is the ultimate choice for best in class comfort and performance. Features:One-piece Synchwire upper design with thermal-welded Teijin TPU reinforcement for precise structural support and enhanced durabilitySoft lace guides to eliminate common hot spots and discomfortsTwin Boa IP1 dials featuring 1 mm +/- adjustment and macro releaseEaston EC90 SLX2 high-modulus carbonStainless steel hardware and replaceable heel padsSuperNatural Fit Kit with adjustable arch supportXT2 anti-microbial fiber top sheet215 grams (per shoe, size 42.5)Buy Giro Footwear from Chain Reaction Cycles, the World's Largest Online Bike Store.

  • Saving you £20

Stans No Tubes Flow S1 Mountain Bike WheelsetDurable and light, the Stan's No Tubes Flow S1 Mountain Bike Wheelset is ready to handle the toughest trails. Multiple World Cup Downhill (DH) winners have inspired the race-ready design of the Flow S1 wheelset making it the ideal addition to any keen rider looking to tackle challenging trails and reach the podium. Strong and Multi-purposeFeaturing reinforced rim walls with a 1.6mm deeper profile, the Flow S1’s offer greater impact strength for an even wider range of use. Despite this, they only have a minor weight increase over Stan’s other models. They’re constructed with a 32-hole spoke count front and rear, using easily replaceable standard spokes. Combined with Stan’s faster-engaging and CNC-machined Neo hubs, this wheelset is the ideal choice whether you ride trail, all-mountain, or enduro.Features:  Durable and lightweight aluminium construction  Wider rim width for more stability with larger tyres  3mm wider than Rapid 30 with no weight gain Developed on the World Cup DH circuit Rim profile optimised for 2.35" -  2.80” tyres  Rim Internal Width: 29mm  Rim External Width: 33.1mm  Rim Depth: 17.6mm  ERD: 566mm (27.5") / 604mm (29")  Spokes: Sapim 2.0/1.8/2.0mm  ETRTO:  584x29 (27.5") / 622x29 (29")  Nipples: Secure Lock brass silver nipples  ISO: 27.5"x33.1mm / 29"x33.1mm  Hub: Stan’s Neo  Tape: 30mm  Hole Count: 32-hole, 32-hole  Valve: 35mm Presta  Rim Material: 6061 Alloy  Max Spoke Tension: 125kgf (1225N)  Max Rider Weight:  114kg (250lbs)  Max Pressure with 2.4" Tyre: 37psi  Max Pressure with 2.80" Tyre: 26psi  Brakes: Disc Freehub Body: Neo Durasync Red Tubeless tape pre-installed  Use: Aggressive Trail, All Mountain, Enduro, and Downhill  Weight: 2034g (27.5”) / 2134g (29”)Technologies:  WideRight: Rims that are too narrow fail to offer sufficient sidewall support and protection to your tyres and create a less stable shape. The result is less control in the corners, less traction on climbs, and more rolling resistance. Rims that are too wide also distort the tyre profile, decreasing traction and control and driving impacts directly into the rim, negating the impact absorbing advantages of a tyre's volume. Stan's WideRight rim widths are designed to strike the perfect balance between tyre volume and sidewall function.  BST (Bead Socket Technology): Bead Socket Technology rims are designed to match the shape of your tyre's bead to create a safer and more secure airtight interface. BST rims secure the bead of the tyre, not the sidewall, creating an airtight seal while allowing the tyre's sidewall to expand to its true, rounder, more effective profile. The result is more traction and less rolling resistance. With lower-profile, less vulnerable sidewalls, Stan's BST rims are also lighter and stronger by design and accelerate more quickly. Buy Stan's No Tubes Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.

SRAM Force eTap AXS 12 Speed Rear Derailleur - Grey - Short Cage}, Grey
  • £279.99

  • Saving you £8

SRAM Force eTap AXS 12 Speed Rear DerailleurFeaturing a tough aluminium cage construction and steel pulley bearings, this versatile rear derailleur is built to withstand the challenges that are associated with road and gravel riding. SRAM has also ensured that this model is AXS enabled, so riders can benefit from easy personalisation and control wherever their journey takes them. Another highlight is its Orbit chain management technology that's specifically designed to keep your drivetrain quiet and secure when travelling on rough roads and gravel. This makes it a great choice of upgrade for riders who want to explore further when the tarmac comes to an end.SRAM AXS Enabled Road Bike Rear DerailleurFast, precise rear shifting is now more attainable than ever. Whether you ride 2x or 1x, tarmac or gravel, the SRAM Force eTap AXS rear derailleur is up for the task. It features Orbit damper technology for quiet, secure chain management over rough roads and capitalizes on larger X-SYNC pulleys for improved durability and efficiency.- Orbit chain management technology keeps the drivetrain quiet and secure- Compatible with both 1x and 2x drivetrains- SRAM AXS enabled, allowing easy personalisation- 36t-max derailleur option is compatible with 10-36, 10-33, and 10-28 cassettes- 33t-max derailleur option is compatible with 10-26, 10-28, and 10-33 cassettes- Larger X-SYNC pulleys for increased durability and efficiency- Compatible with existing eTap batteriesFeatures: Cage Material: Aluminium Pulley Bearings Material: Steel Use: Road, Gravel Speed: 12 speed Max Tooth: Multiple options available to selectTechnologies: AXS Enabled: AXS is SRAM's bike component integration system that connects electronic bicycle components and software. Control: AXS lets you connect your AXS-enabled components to a mobile app, where you can assign custom actions to your controls. Everything speaks the same language, and you can even combine road and mountain bike parts to build the party bike of your dreams. Personalise: Wireless controls open the door to new levels of customisation. With AXS, you can personalise your component behavior to match your riding style and preferences. Turn on enhanced shifting modes, or reassign shifting actions. Measure: The AXP Mobile App and AXS Web allow you to monitor your bike's performance and readiness. It's an easy way to keep tabs on your battery levels—including the CR2032 batteries in eTap shift levers—and keep AXS component firmware up-to-date. AXS Web analyses your ride files specific to shifting, gear use, power zones, and tyre pressure, so that you can quickly and easily learn more about how your bike is working for you and consider adjustments. X-Sync: SRAM X-SYNC chainrings provide the highest level of performance and durability. The SRAM X-SYNC tall square teeth edges engage the chain earlier than traditional triangle-shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC rings are an integral part of the SRAM 1x drivetrain. Accept no imitation. Orbit: Orbit technology is an innovative form of derailleur motion control. It utilises silicon fluid as part of an elegant and ultra-lightweight damper system. Compared to a standard friction clutch system, Orbit technology places no additional resistance on the rear derailleur's spring when under slow or light movement. This means easier shifting and rear wheel removal. And while riding, the fluid damper reduces chain bounce. It's rock-solid reliability for both 1x and 2x systems.Manufacturer's Part Numbers: 00.7518.121.001 Grey Short Cage Max 33t 00.7518.136.000 Grey Medium Cage Max 36tBuy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
