Note: These sprockets move the belt line further
outboard, allowing for easier integration with mid-drive E-bike motors. When using these sprockets, it may be necessary to increase the clearance between the
shifter cable and the rear sprocket. Shimano has released new special cassette joints for this
purpose. Please note the E-bike integration manual by Gates Carbon Drive.
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
STRONG: The instant engagement and smooth feel is unlike anything you've
experienced before. You've got to ride it to believe it.
Gates Carbon Drive has introduced a new line of sprockets called SureFit. The patent pending sprockets have a flexible interface for the 3-lobe design of some internally geared hubs such as the Shimano Nexus/Alfine series. This flexible design adjusts to provide the proper fit on a broad range of tolerances. This means a better fit on Shimano hubs, as well as allowing integration on all SRAM brand internally geared hubs with the 3-lobe interface.
