Bionicon eco

Bionicon EcoThe Bionicon eco is the 3rd generation of the innovative and award-winning chain guide for single, double and triple ring drivetrains. The eco is a significantly improved and simplified design, so good that the v.02 is being discontinued. You deserve the best performing and toughest at a much lower price.


The eco is more effective and virtually eliminates dropped chains, chain slap and rattles, quieting your bike and protecting your chainstay, which is an especially big deal if you have a carbon bike. If you already have a clutch type derailleur the eco will give you the extra reassurance that your chain will stay put and give you the most effective chain retention you can have short of a full on DH type chain guide.
