The application of The Spine Concept™ to handlebar shape is the result of fi’zi:k’s research with riders of 3 UCI World Tour Teams that were riding fi’zi:k saddles. A correlation was found between the saddle shape each rider was using and the handlebar shape they were riding. Just as your choice of fi’zi:k Spine Concept™ saddle shape is guided by your degree of spinal flexibility and subsequent pelvic rotation, fi’zi:k offers this same concept to find your most comfortable handlebar shape. The Snake Handlebar: If you are very spinally flexible (far less than 90 degrees between your straight legs and your back when bending over as far as you can, keeping your legs straight a shoulders’ width apart), you are a Snake. You are better able to reach further and get down lower to use the full radius of more rounded, classic-style, deeper-drop handlebars. You will prefer the Snake Handlebar because it has a longer reach and deeper, classic-style drop. The Chameleon Handlebar: If you have an intermediate degree of spinal flexibility (approximately 90 degrees between your straight legs and your back when bending over as far as you can, keeping your legs straight a shoulders’ width apart), you are a chameleon. You are better able to reach further, but perhaps you can’t get down quite as low on the handlebar drops as a Snake would be able to. You will prefer the Chameleon Handlebar because it has a longer reach but a shallower, more ergonomic-style drop. The Bull Handlebar: If you have a relatively low degree of spinal flexibility (more than 90 degrees between your straight legs and back when bending over as far as you can, keeping your legs straight a shoulders’ width apart), you are a Bull. You will not be able to reach as far or bend as low as a Snake or a Chameleon would be able to. You will prefer the Bull Handlebar because it has a shorter reach and a shallower, more ergonomic-style handlebar drop.

Fizik Luce R1 Women's Road Bike SaddleWhen Fizik was creating the Luce R1 saddle, they constructed an all-new design in order to produce a women's saddle that offers outstanding performance and comfort over long distances.Advanced ShellThe shell of the Luce R1 combines three different sections, consisting of a central nylon spine that's reinforced with carbon fibre and two thermoplastic elastomers. This ensures the Luce R1 provides the ideal mix of low weight, strength and flexibility.Central Cut-outAnother great feature of the shell is that it has a long central cut-out. Fizik calls this its IschialFlex technology, as it provides flexible support for the sit bone area. It also reduces pressure on sensitive areas so you can enjoy consistent comfort even on the longest rides.Carbon Fibre RailsIn addition to the highly-advanced shell, this saddle features a narrow carbon Mobius rail construction. These rails don't just reduce the overall weight, they maximise power transfer and dampen vibrations from the road.Spine Concept EvoThis saddle is available in two different sizes. Within Fizik's Spine Concept Evo saddle fitment guide, the width of Fizik's “Regular” saddles are best for women with relatively high power output to bodyweight ratios. Fizik's “Large” saddles are best for women with low power output to bodyweight ratios.Features: Cover: IschialFlex Shell: Carbon reinforced Nylon Rail: Carbon rail Length: Regular: 281x144mm; Large: 281x155mm Integrated Clip System compatible Weight: Regular: 175g; Large: 185gBuy Fizik Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Fizik R2 Vento Powerstrap Aeroweave Road ShoesA new breed of super-light and super-ventilated racing shoes, the Fizik R2 Vento Powerstrap Aeroweave Road Shoes deliver race-winning, rival-dropping pedalling performance alongside outstanding levels of cool airflow. Fizik's engineers set themselves the task of creating a super-light shoe that made no sacrifices to foot support and pedalling performance. It also had to be incredibly breathable too. The result is the R2 Vento Powerstrap Aeroweave Road Shoes. Aeroweave TechnologyAeroweave is an innovative woven fabric, interweaving lightweight nylon fibres with filaments of thermoplastic polymer. This combination creates a net-like structure that is highly durable but offers incredible levels of ventilation. Not only that, Aeroweave offers a supple fit, moving and cradling the foot for comfort while retaining the full support you need for a stable and efficient pedal stroke. Powerstrap PerformanceThe R2 Vento Powerstrap Aeroweave secure your foot with a simple but ingenious configuration of the traditional strap system.In order to offer stability and comfort throughout your ride, the Powerstrap system features a lightweight and reliable hook and loop strap system that pulls together the two sides of the upper. However, unlike a traditional system, the Powerstraps fully wrap around the upper. This provides even pressure across the whole foot, the ribbon wrapping around your foot for an unrivalled level of riding comfort. Another benefit is a much more aero finish than a traditional strap system. 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:Aeroweave - extremely breathable, high tenacity net-like upper structurePowerstrap - foot-wrapping Velcro closure designed for an enveloping fitR2 carbon outsole - optimized cleat positioning, high stiffness andlightness tuned for power transferR2 outsole - full carbon, stiffness index 103-bolt cleat compatible (cleats not supplied)Weight: 196g (size 42)Buy Fizik Footwear from Chain Reaction Cycles, the World's Largest Online Bike Store.
