There are several more equipment choices to be made after you have selected your component group.
Belt Tensioners
A belt tensioning device is essential for achieving the correct tension during assembly as well as maintaining optimal position of the rear hub.
Guide Pulley
While not essential in all situations, we offer a guide pulley device that also serves as a belt tensioning mechanism. The guide pulley eliminates the possibility of belt skipping caused by a sudden shockload on the drivetrain (for example, starting in a high gear).
Crank Arms
CDRIVE™ front sprockets require a regular 4 arm, 104mm bolt circle diameter crank arm set which match the chainline requirements of your chosen rear hub. Front sprocket spacer shims can be used to reach the required chainline.
Rear Hub Constraints
The rear hub should be either an internal gear hub with a regular 3-spline interface (34.5mm diameter), or a 9-spline Shimano style hub with internal freewheel for a single speed application. Both are shown below.
Note: there is no single speed freewheel available with CDRIVE™ sprockets for a regular screw on hub.
