The BioLogic FreeDrive encloses the bicycle chain to keep the rider’s clothing protected from grease and dirty spray. The FreeDrive’s ingenious design moves with the chain so it is friction free, unlike with some other chain protection methods. It also reduces chain vibration and noise. With a FreeDrive, you can say goodbye to bulky chainguards.
