Fizik Cyrano R5 Road Handlebar - Black - 75 Reach 125 Drop, Black
  • £19.99
  • RRP £39.99
  • Saving you £50

Fizik Cyrano R5 Road HandlebarThe Cyrano R5 is the entry-level handlebar from Fizik. It is made from 6061 anticorodal aluminium that makes it incredibly lightweight and great at reducing road vibrations. It offers the ability for riders to incorporate the flexibility of Fizik's Spine Concept system at a lower price point.Just as your choice of Fizik Spine Concept saddle shape is guided by your degree of spinal flexibility and subsequent pelvic rotation, Fizik offers this same Spine Concept guideline to help you choose your most comfortable road handlebar shape.The application of The Spine Concept to handlebar shape is the result of Fizik's research with riders of 3 UCI World Tour Teams that were riding Fizik saddles. A correlation was found between the saddle shapes each rider was using and the handlebar shape they were riding.The Snake Handlebar: If you have a very flexible spine (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, and 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.Features: Material: Anticorodal 6061 aluminium Flare of drops: 3 degrees Diameter: 31.8mm Weight: 310g (size 400mm, centre to centre)Buy Fizik Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Nukeproof Horizon Top Headset CupThe Horizon Top Headset Cup from Nukeproof comes from a new range that uses titanium coated race bearings with stainless steel balls. The titanium coating is applied using “Physical Vapour Deposition” which means that the material is vapourised in a vacuum environment and then deposited on the bearing races as a composition coating.This process allows the structure, density and stoichiometry of the coating to be controlled allowing the exact attributes in our design brief to be achieved. The coating is 0.000118” thick and has a molecular bond to the bearing races so it won’t wear off or corrode. The bearing is ABEC 5 certified which means that it has passed tests which include ID and OD tolerance’s, roundness of ball, the trueness of faces & surfaces as well as noise testing at high RPM making it the perfect bearing for use in a headset.These bearings have been designed for use in the harshest weathers and have gone through various tests by the Nukeproof team during development so they are 100% confident in their performance.
