Gates Carbon Drive System
The technology behind Gates Carbon Drive System is rooted in high horsepower motorcycles and dragsters. Now, this high performance technology has been perfected for a wide variety of bicycles. At the core of the drive is the Carbon Drive belt. Custom made, this carbon-fiber belt is a strong and efficient replacement to a traditional bike chain. The drive is completed with the innovative sprocket designs and your choice of internally-geared or single-speed hub. The patented Gates Carbon Drive System gives you a longer-lasting, lower-maintenance drive, and most importantly, an unbelievably awesome ride.
CLEAN - LOW MAINTENANCE: No lube required = no grease stains. It sheds dirt and grime and cleaning with water is easy. Just get on it and ride.
QUIET: No chain = no chain clatter. It's spooky quiet.
LIGHT: Gates Carbon Drive weighs less than a chain drive. Lighter weight means
higher performance.
STRONG: The instant engagement and smooth feel is unlike anything you've
experienced before. You've got to ride it to believe it.
