• The whole construction is 2 part so allowing fitting over the gear cable & chain with no disassembly! Fitting is even quicker than before.
• 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.
• The c.guide can still be fitted over the gear cable meaning the cable hinge is not needed. This gives a small weight saving & a cleaner look.
• The guide tube now features a pivot & follows the chainline much better whether with 2 or 3 chainrings. Reduced chain noise & lower wear are the result.

In the not so distant past, the height of cool was…. white Onza Porcupines, Purple Bar Ends, a Flite Titanium Saddle and a DCD (Daves Chain Device). The DCD bolted onto your chain stay and the chain fed through it. Bionicon has a modern take on this, the C-Guide. There are many other chain systems out there now, and the recent introduction of the clutch derailleur, means the C-Guide has much more competition that the DCD ever did.
