BioLogic FreeDrive

By -
  • Sleek, low-friction chain protection
  • Reduces chain vibration and noise
  • Keeps clothing (and other passengers, if you commute) free from grease
  • The looks and cleanliness of a belt drive with the efficiency of a chain drive
The BioLogic FreeDrive chain cover encloses the bicycle chain to keep the rider’s clothing protected from grease and dirty spray. Due to its ingenious design, the FreeDrive moves with the chain – unlike some other fixed chain protection methods that add friction. It also reduces chain vibration and noise. With a FreeDrive, you can say goodbye to bulky chainguards.
  • Compatible only with single speed and multi-speed internal hub gear bikes
  • Requires 17-tooth rear cog or more
