Balancing aerodynamics, lightweight and durability, the Reynolds ARX 58X Carbon Clincher wheelset offers class-leading all-round performance. Equipped with a 58mm carbon fibre rim, this wheelset slices through the air like a knife, helping you to motor over flat and rolling courses. However, weighing just 1635 grams per pair, they’re certainly no slouch on the climbs either. Constructed with a wider, tubeless-compatible rim, they even allow riders to seat tyres for more comfort, grip, speed and puncture protection. Thanks to the Ctg2 treated brake track, this wheelset is also up to 30% better at dissipating heat than competitor carbon clincher wheelsets, making them much more reliable under sustained braking. Paired with a set of Reynolds allroad hubs, the Reynolds ARX 58x Carbon Clincher wheelset spins exceptionally smoothly. To maximise stiffness and durability even further, these hubs are laced to the rims via 20 CX aero spokes on the front, and 24 on the rear. Importantly, Reynolds are so confident in the durability of this wheelset, that they even come with a lifetime warranty.

Accurate Readings in all Conditions Shimano have extensively tested this new power meter system to ensure its accuracy and reliability in all weather conditions. The chainset is equipped with dual sided and internally hard-wired crank arm strain gauges, which provide a ±2% power measurement accuracy regardless of your pedalling position. Easy to Maintain The power meter is powered with a simple rechargeable battery for easy maintenance and can be updated wirelessly. As it is mounted to the crank arms 4-arm spider, you can change the chainrings without having to worry about affecting the power measurement. Lighter and stiffer Although the crank arms and spider arms are noticeably bigger to increase stiffness, the overall weight has dropped by 7g over the previous edition of Dura-Ace. The chainset has been adapted to work with disc brake road bikes that generally have 135mm rear hub spacing and shorter chainstays without the need to increase Q-factor thanks to its wider chainring spacing. This Compact version features a 50/34T chainring profile to offer an excellent rider tuned gear combination for varied conditions from flats to high mountains.
Fast Forward Drift DT240 Carbon Gravel Disc WheelsetProviding durable, agile and lightweight performance, this high-quality wheelset is Fast Forward's first-ever dedicated model for gravel bike riding. It features a full carbon rim construction, which gives it exceptional stiffness and versatility without adding any unnecessary grams to your ride. Fast Forward has also equipped it with Centrelock disc brake compatibility, so riders can enjoy powerful and consistent braking operation wherever their ride takes them. Another highlight is its tubeless-ready technology, which means that you'll benefit from lower rolling resistance, increased comfort and stability, as well as fewer chances of flats or punctures.Adventure-Ready Carbon Gravel WheelsetWhile weight is normally one of the most interesting specifications to check, Fast Forward takes a different approach when it comes to producing top-quality wheels. In the brand's choices, weight is important but should not compromise other areas such as durability and agility. For the Drift, it was even more important as they need to last and cope with whatever comes on your gravel paths. You will find this in the DT Swiss Aerocomp spokes and brass nipples for example which - when put together with the updated DT240 EXP hubs - make a fantastic set. The thicker spokes also offer more rigidity and durability and can take some hits.Agility is brought together by the rim's height of 36mm combined with the Aerocomp spokes. These ingredients bring you stiffness and more power transmission when you put the wheels in motion. All your energy will result in more and easy miles off-road and thus more time to enjoy your ride!Hookless Design for TubelessThis wheelset's hookless rim design features an internal width of 24mm only to be used with tubeless tyres. A special carbon layup is chosen to deal with higher impacts when riding on low tyre pressure on more heavy gravel roads. It offers the possibility for a broad range of tyre options from 30mm up to 60mm and with that no excuse for the terrain you will attack.The set puts merely 1515 grams on the scale and comes as a complete package with tubeless tape and valves packed nicely in a protective FFWD wheel bag. Drift is the first dedicated gravel wheelset that marks the start of this category for Fast Forward.Features: Material: Full Carbon Clincher Use: Gravel, Adventure Axle: Front: 12x100mm; Rear: 12x142mm Type: Clincher with Hookless design Rim Depth: 36mm External Rim Width: 30mm Internal Rim Width: 24mm ETRTO: 24-622 Brake Type: Centrelock Disc brake Max Tyre Pressure: 72 psi Min/Max Tyre Size: 30mm/60mm Tubeless Ready: Yes Disc Brake Compatible: Yes Rim Brake Compatible: No Inner Tube Compatible: Yes Tubeless Compatible: Yes Tubular Compatible: No Hub Type: DT Swiss 240 EXP (2:1) Bearings: Cartridge; Stainless Steel Spoke Type: DT Aerocomp Spoke Style: Straight-pull Spoke Count: Front: 24; Rear: 24 Nipples: DT Pro Lock Brass 15mm Rim Tape: Tubeless tape; 27mm Single or Pair: Pair Included: Wheelset, pre-installed tubeless tape, pair of alloy tubeless valves, tubeless instructions and a high quality padded wheel bag Max Rider Weight Limit: 120kg/265lbs Weight: 1515g (Front: 710g; Rear: 805g)Manufacturer's Part Numbers: ASDRIFT36FCC240S Black 700c Shimano 9/10/11sp ASDRIFT36FC240XD Black 700c SRAM XDRBuy Fast Forward Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.

Just like high-quality frame tubing, a hollow crank arm can provide amazing strength and rigidity at very lightweight. The Best Balance of Stiffness, Strength and Weight The concept of Hollowtech II technology is focused on producing a superior crankset that will maximize a rider’s power transfer. The rigidity of the crankset ensures pedalling efficiency while its low weight, a key element of the crankset, aids in cycling longer distances over which the rider needs to pedal more. Naturally, Shimano strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. The addition of Hollowtech II technology integrates the bottom bracket axle with the right crankarm for more stiffness and weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedalling stability, allowing for more efficient power transfer. The Shimano Dura-Ace R9200 12 Speed Power Meter has been developed by pursuing the optimum balance of stiffness & rotating performance in a lightweight and beautiful crankset design.

The ENVE Foundation AG25 Gravel Wheelset is designed for everything from bike packing to gravel racing. “AG” stands for “Adventure Gravel” and this is the guiding principle behind the AG25. Part of ENVE’s new Foundation collection, the AG25 brings ENVE’s core technologies and trickle-down features from the ENVE G Series to riders seeking out adventure and ultimately looking to ride for the fun of it. The AG25 is a 700c gravel wheel that can take tyres up to 50mm, responding perfectly to the larger clearances of modern gravel and adventure bikes. The rim shape was developed by ENVE that would smooth out the ride while still delivering a confidence-inspiring feel when it comes to handling. The AG25 uses ENVE’s Wide Hookless Bead to minimise the chance of pinch flats. The wider leading edge of the rim disperses any impact from debris or potholes over a wider area. This leads to a 60+% improvement in pinch flat resistance as well as a 30+% improvement in impact strength. Drilled spoke and valve holes mean the carbon fibres in the AG25 run through the wheel uninterrupted as opposed to being cut. This makes for a stronger, lighter rim structure. Another benefit is that ENVE can control the shape of the rim at the spoke/nipple interface with greater precision. ENVE rims feature a conical nipple seat that prevents premature spoke fatigue while also ensuring wheel-build reliability. The AG25 uses the ENVE Foundation Road Hub, which uses ENVE’s core hub technologies. The hub shell uses simplified machining without compromising flange geometry and wheel build stiffness. The drive mechanism uses Instant Drive 360 technology and a 40t ratchet to deliver responsive engagement, minimal drag, and low maintenance performance. The bearings are premium full contact sealed NTN steel bearings. The Rotor attachment is center lock. The AG25 is also available with the Industry 1/1 hub. The ENVE Foundation AG25 Gravel Wheelset comes with ENVE's leading Factory Limited Warranty and Incidental Damage Protection. The Factory Limited Warranty protects buyers for five years from defects in material and workmanship, while the Incidental Damage Protection gives protection from damage caused to their wheels while riding, crashing or transporting bikes. Beyond these three years, there is a prorated discount structure available.
Zipp 404 Firecrest Carbon Tubeless Rear WheelZipp's legendary speed weapon, the 404 Firecrest, is better than ever. This go-to rim-brake rear wheel is, for the first time, tubeless ready. That means you can run reduced tyre pressure for reduced rolling resistance and increased cornering grip and compliance without the risk of pinch flats. This rear wheel's 58mm rim depth is a classic that has carried athletes to victory in every kind of event and situation - every triathlon distance, breakaways, field sprints and hilly finishes.

If you had to choose just one wheel for road riding and racing, the 404 Firecrest Tubeless is a savvy and speedy choice.ABLC SawtoothThe Sawtooth dimple design consists of 12 nodes that are specifically clocked to start aerodynamic shearing at a rate of 50hz at a rider speed of 20mph. Sawtooth accomplishes this by inducing small sheet vortices that shed at a low magnitude, but at a higher natural frequency, thus decreasing the laminar bubble effect on the aerodynamically shielded side of the rim's profile to further reduce high yaw drag and improve crosswind stability. ABLC Sawtooth dimple design helps manage air flow around the rim and contributes to creating a faster, more stable wheel.Features: Rim Material: Carbon with UD Fibre finish and adhesive decals Use: Road Axle Type: QR 135mm (quick release) Internal Rim Width: 19mm Rim Depth: 58mm Rim Profile: Symmetrical Brake Compatibility: Rim Brake Size: 700c Tyre Compatibility: Clincher, Tubeless Ready Surface Texture: ABLC SawTooth Nipple Material: Aluminium Nipple Anti-rotation: Sapim Secure-loc Spoke Type: CX-Ray - Black Spoke Count: 24 Spoke Pattern: 2 Cross Driver Body Type: SRAM XDR Axle Material: Aluminium Bearings: Cartridge - Steel Driver Mechanism: 6 Pawls Leaf Spring Driver Body Material: Aluminium Max Tyre Pressure: 125psi Max Recommended Rider Weight: 250lbs Single or Pair: Single rear wheelTechnologies: New Zipp graphics and cosmetic identity that scream speed.
