Material: Uni-Directional Carbon Width: 400/420/440/460mm Reach: 85mm Drop: 135mm Flare of Drops: 3 degrees Weight: 205g (size 420mm, centre to centre)The Fi zi:k Cyrano R1 Chameleon Carbon Handlebar is the mid-range handlebar. Made from uni-directional carbon, this is both strong and lightweight. 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 Spine Concept guideline to help you choose your most comfortable road handlebar shape. These products are being ridden at UCI World Tour level by AG2R Pro Cycling Team. 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.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 (85mm) but a shallower, more ergonomic-style drop (135mm).
