Prime 343 Carbon Rear Road Disc WheelThe Prime Carbon Disc Wheel is a rear race wheel that features a full carbon disc with a rim braking surface and is tubeless ready. Engineered to provide the greatest aerodynamic efficiency, power-transfer and outstanding crosswind stability, this wheel was created for top-level racing. Plus, it's tubeless-ready, which means it rolls faster, is lighter and provides greater grip than a standard clincher setup. Also, the tubeless setup eliminates the possibility of getting pinch flats.Features: Material: Carbon Fibre Tubeless Compatible 4 Pawls with 36T Ratchet ring Shimano Freehub body Internal Width: 18.7mm External Width: 25mm Weight: 1122gBuy Prime Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
Manitou Mezzer Expert Suspension ForkThis enduro suspesnion fork features 37mm stanchions that are constructed from 7000 series aluminium and Reverse Arch technology, using the same chassis as Manitou's Mezzer Pro suspension fork. This allows it to deliver exceptional stiffness and strength, while also being incredibly lightweight at only 2030g (27.5” option). As a result, the Expert is the second lightest fork in the Enduro category, second only to the Mezzer Pro of course. Another highlight is it comes race-ready with an Expert Air air spring with Incremental Volume Adjust (IVA) for an impressively smooth feel as you charge across challenging terrain conditions. It also offers a wide range of adjustment features from its Variable Terrain Tune (VTT) damper that can easily be tweaked to suit any terrain thanks to its six positions. With adjustable Air, Air Volume, Rebound, 6-position Compression (Open, Trail, Lock), this suspension fork is the smart choice for anyone looking to dive into the Enduro Fork market.Enduro Fork with Expert Air SpringExpert Air is derived from Manitou's Dorado Air system and features a unique balancing valve that equalizes the positive and negative air chambers during the air fill process. This valve is activated only when the pump is threaded completely onto the valve. This gives the spring rate a smooth and consistent feel without any flat or dead spots in the stroke.Six Position Variable Terrain Tune (VTT) DamperAdjusted through a single external compression adjuster, both high-speed and low-speed damping characteristics are changed simultaneously when turning the knob. The damper features a fixed shim stack and a secondary shim stack that is preloaded by the external adjuster. In positions 1 and 2 there is an open flow path through the compression damper. In positions 3-6, the adjustable shim stack comes into contact with the piston, increasing platform force. This design provides a wide tuning range that combines the benefits of a low-speed platform and a high-speed progressive tune that can suit any terrain through 6 positions.Hexlock SL AxleManitou's patented hex axle locks the lower legs in place, eliminating rotation around the axle providing unsurpassed stiffness in a lightweight tooled package.Features: Leg Material: 7000 Series Butted Wall Aluminium Crown Material: Forged Aluminium, Hollow Bore Leg Diameter: 37mm Use: Enduro Axle Size: 15x110mm Hexlock Steerer Diameter: 1 1/8-1.5" tapered Air Spring: Expert Air with Incremental Volume Adjust (IVA) Compression Damping: Six Position Variable Terrain Tune Rebound Damping: Open Cartridge adjustable TPC Adjustments: Air, Air Volume, Rebound, 6-position Compression (Open, Trail, Lock) Offset: 37/44OS (27.5" Option); 44/51OS (29" Option) Ride Height: 534-574mm (27.5" Option); 554-594mm (29" Option) Travel: Multiple options available.

Expert Air offers ultimate sensitivity featuring a self-equalizing negative air spring. IVA (Incremental Volume Adjuster) allows you to modify your positive air chamber volume by rearranging self contained spacers. You'll never lose a volume spacer again. VTT-6P damper provides 6 easy clicks to dial in your damping for all types of terrain. Integrated fender can be installed/removed by three small screws threaded into the arch of the fork. TSR (Trail Side Relief) valves on the back of the lower legs allow you to bleed off built up air within the lower legs to keep things butter smooth between service intervals.Manufacturer's Part Numbers: 191-36964-A101 Black 29" x 180mm 44mm 191-37137-A101 Black 27.5" x 180mm 37mm 191-36964-A103 Black 29" x 160mm 44mmBuy Manitou Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Shimano Dura-Ace R9270 C36 Carbon CL Disc WheelThe Dura-Ace R9270 C36 Carbon CL Disc Wheel from Shimano is a Tubeless Ready mid-depth-profile wheel that's versatile for steep climbs, fast sprints and long days in the saddle. It features a 36mm-profile full-carbon rim and a Centre Lock disc rotor mount while being compatible with 12mm E-Thru axles, this race-ready wheel is fast, aerodynamic and stable for road racing anywhere.With stunning acceleration, the new Dura-Ace R9270 C36 wheelset will change the way you experience climbs, corners, even stoplights. This is because it isn't just how much a wheel weighs but where the weight is on the wheel that matters. The all-new C36 design shaves mass at every opportunity but especially at the rim. The result is a lively wheelset that can transform your ride. Lighter, Wider and Faster Carbon Road Race WheelWith both a lighter, wider all-carbon rim and a lighter hub, the new Dura-Ace C36 won't shy away from a day of climbing. The new rim is 36 mm deep and still delivers good aerodynamic efficiency despite its gossamer weight. Meanwhile, the hub features an alloy freehub body and a new engagement mechanism for increased rigidity. Centre-Lock Disc Rotor MountThe Centre Lock system makes an easy rotor installation possible with a spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency. D2 Aerodynamic Rim ProfileAerodynamic performance is affected by wind direction. To create the D2 rim, Shimano engineers considered both frontal and crosswinds, aiming to achieve optimal performance in real-world riding conditions. Extensive prototype testing, in the wind tunnel and on the road, proved that a wide rim shape with a deep tire bed performs best across a wide range of conditions. At yaw angles ranging from 0 to 15 degrees, the Shimano D2 rim profile reduces air drag better than others aero shape rims. This rim design also boosts lateral wheel stiffness and offers improved vertical compliance for increased control, comfort and durability on the road. Rear Wheel OPTBAL Spoke SystemThe OPTBAL rear wheel spoke system features 21 spokes—14 on the drive side and 7 on the non-drive side. Cassette spacing in today's wheels produces unbalanced tension in traditional 1:1 spoke systems. This unbalance is intensified with the 11-speed cassette, producing nearly double the tension on the drive side spokes. Generally, high and low tension spokes have respectively tendency toward breaking down and coming loose spoke nipples. Unbalanced tension affects durability and strength. The OPTBAL design rebalances spoke tension, enhancing wheel rigidity and strength for a more durable wheel. Shimano E-Thru Axle SystemThe tool-less type thru-axle skewer system optimizes rigidity and weight balance and enables easy operation with a reliable internal cam mechanism. The 15 mm thru-axle system is 15% stiffer torsionally and 25% stiffer in transverse shear than a traditional 9 mm quick release front axle system. High rigidity is secured while keeping the optimum weight balance. The E-Thru axle hub system minimizes the distortion of suspension while maintaining lightweight for riding around sharp corners at high speed.
