Fizik Vento Infinito Carbon 2 Road ShoesDeveloped, tested and refined with professional cyclists, the Fizik Vento Infinito Carbon 2 Road Shoes give you unrivalled levels of comfort and pedalling efficiency. Stamp on the pedals and enjoy the instantaneous response. Supple and StrongWith an upper made from Microtex, the Vento Infinito Carbon 2 Road Shoes give you a fit that is both supple and strong, providing comfort from the very first pedal stroke. It also gives a precise and supportive fit of the foot, ensuring a stable platform during the whole of your crank rotation, driving pedalling efficiency.Customised Fit - BOA Fit SystemTo give a customisable and comfortable fit, the Vento uses the dual Li2 BOA fit system. The Li2 dials have been redesigned to offer a lower profile, marginally improving aerodynamics while also making them less vulnerable to being accidentally hit. Each dial gives quick and easy micro-adjustment, with independent adjustment of the forefoot and instep. Fine-tuning the fit to your particular foot shape is now remarkably easy. R2 Carbon OutsoleThe stiffest and lightest sole unit in the Fizik range, R2 Carbon Outsole delivers incredible responsiveness, with power transferred to your pedals with outstanding efficiency. Jump for a sprint or attack a climb and you're rewarded with immediate acceleration - only fitness is holding you back.Efficient pedalling is also optimised thanks to the cleat track position. This has been set further rearwards to improve pedalling dynamics, reduce knee compression and power transfer - it's especially well-suited to very aggressive, forward aero riding positions.Cleat GuidanceThese Cycling Shoes are compatible with road bike pedal systems that use cleats with 3-bolt standards, such as: Look Delta and Keo, Shimano SPD-SL, Speedplay Light Action, Zero, X-Series (via 3-hole adapter plate), Campagnolo Pro-Fit, Mavic Zxellium, Time Iclic/Xpresso and Time Impact.Features:Knitted PU laminated mesh upperLi2 Dual Zone BOA Fit SystemIndependent fit adjustment for instep and forefootDynamic Arch Support 2.0: tailored fit of the plantar archR2 carbon outsole - full carbon unidirectional, stiffness index 10/103-bolt cleat compatible (cleats not supplied)Weight: 225g (size 42 - 1/2 pair)Buy Fizik Footwear from Chain Reaction Cycles, the World's Largest Online Bike Store.

Sector 9i Carbon Front Mountain Bike RimReady for shredding the trails with your friends as well as exploring new off-road routes on your own, this carbon MTB rim is engineered for maximum performance. It features a hard-wearing unidirectional carbon fibre rim construction, which allows you to benefit from its fantastic strength without adding any unnecessary weight to your ride. Sector has taken this model's design a step further by also integrating TeXtreme Innegra into the layup of the rims. This gives it 75% more impact resistance than standard carbon rims of the same profile. The 9i MTB rim is significantly more resistant to wear and tear and less prone to catastrophic failure.So what is Innegra?Innegra is a fibre derived from polypropylene that exhibits some highly beneficial properties, including high strength-to-weight ratio, resistance to damage, vibration damping and energy dissipation. The TexTreme fabric used in the layup of 9i rim is a Spread Tow fabric built from a hybrid of Innegra and T700 carbon fibres.The Spread Tow layout is significant because it also contributes some positive attributes - the fibres are straighter (reduced crimp therefore higher strength) and it facilitates the use of less resin (lower weight). In the 9i rim the Spread Tow fabric is used on the outer layer of the rim, giving it the unique checkerboard pattern.Sounds good, but what does that mean for a rim? Significantly more compliance... Under a lab test the 9i rim was 50% more vertically compliant than a unidirectional T700 carbon rim of the same profile. This test involves loading the rim with a 100kg weight, in which the 9i rim exhibited a deflection of 15.74mm compared to 10.55mm on the standard T700 rim. It is widely acknowledged that vertical compliance is important for damage reduction (less likely to crack), a reduction of fatigue and to improve traction. Such an improvement in vertical compliance also brings a radically improved ride quality to the 9i wheelset.The Innegra equipped rims do not have the associated harsh stiffness of regular carbon wheels. Significantly more impact resistance... In the lab the 9i rim was able to handle impacts of almost double the standard required for MTB wheels by the UCI. The 9i rim withstood an impact of 140J compared the UCI stipulated requirement of an 80J impact, making it 75% stronger than the UCI requirements.In real world terms, the 9i rim can handle the equivalent of dropping a 15kg weight from a height of up to 1.08 metres onto the bare rim, thus making it 18% stronger than a recognised leading competitor who has published their data. Much less weight... Despite offering strength and compliance advantages, the use of Innegra also allows the construction of an extremely lightweight rim. The Innegra equipped 9i rim weighs just 428g (29”).Features: Rim Material: T-700 Unidirectional Carbon Fibre; Outer layer: TeXtreme Plain Weave Spread Tow Carbon Fibre and Innegra S Hybrid Use: MTB Rim Size: 29" Holes: 28h or 32h options Rim Width: (Internal) 29mm; (External) 35mm Rim Depth: 25mm ERD: 591mm Tubeless: Yes Single or Pair: Single Weight: 428gBuy Sector Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
