Sprockets (the front / crank component), are supplied with a lip on the outside - furthest from the frame
Cogs (the rear component), are supplied with a lip on the inside- toward the center of the frame.
Centerline of the sprocket or cog is defined as the point 5mm on the tooth from the lip of the belt drive component
It is imperative, in the belt drive system, that the bottom bracket shell and the rear axle be parallel. Any misalignment will cause either the belt to rub against the lip, or cause the belt to work its way off the sprocket and cog.
We are currently running at maximum capacity. Due to this and the high demand for new products we are releasing we will be discontinuing production on all Gates Carbon Drive compatible components. We are sorry for any inconvenience this poses.
If you would like to order any standard or custom belt drive items not currently in stock, please place your order on or before October 5, 2012. After October 5, 2012 we will offer any remaining belt drive inventory for purchase. Once this remaining belt drive inventory is gone, it will no longer be available for purchase.
