Frame Design

Rear triangle
Unlike a typical bicycle chain, the CDRIVE™ belt cannot be opened for installation. Therefore, we recommend one of the following rear triangle configurations.

Configuration 1: a rear triangle which can be temporarily opened at the dropout.

Configuration 2: a rear triangle which includes a raised drive-side chainstay.

Frame Stiffness
It is essential that the rear triangle of the frame be sufficiently rigid, including the bottom bracket, in order to avoid undue flex which can affect belt alignment.

Belt Tensioner /Droputs
The Dropouts should be near or horizontal and allow for some form of belt tensioning device.

Adjustability tolerances
Every CDRIVE™ sprocket and belt combination has a corresponding chainstay length. The dropouts you design should allow for at least + /- 10 mm adjustability.

Please note that the terms chainline and chainstay are bicycle industry standard terms. The CDRIVE™ system is a belt drive system. Chainstay length refers to the center-to-center distance from the bottom bracket spindle to the rear axle.
