The most innovative chain retention system, the Bionicon C.Guide V.02 brings with it a load of features. Split design: The whole construction is 2 parts, allowing fitting over the gear cable and chain with no disassembly! Universal hinge: The c.guide v.01 required the gear cable to run along the underside of the chainstay for optimum fitting. Version v.02 can be fitted to any bike with a normal chainstay design. This increases the number of potential users enormously. Cable hinge: The c.guide can still be fitted over the gear cable meaning the cable hinge is not needed. This gives a small weight saving and a cleaner look. Pivot tube: The guide tube now features a pivot and follows the chainline much better whether with 2 or 3 chainrings. Reduced chain noise and lower wear are the result. The C.Guide comes in black, red, blue, green, pink and gold colour options.
