Bushnell EBB Shims


$20.00

We are now making aluminum shims for fitting our Bushnell eccentric into a 55mm and 57mm I.D. bottom bracket shell.

This means that the Bushnell eccentric bottom bracket can fit in almost any bicycle or tandem that uses an eccentric.

Wondering whether you need a shim, or which size shim you need? If you own a Rodriguez, Erickson, Bushnell, Cannondale, Co-motion, or GT Ruckus, you do not require a shim. Otherwise, we recommend measuring the inner diameter of your bottom bracket shell with a set of calipers or contacting your frame manufacturer for specs. A Bushnell EBB will fit without a shim into a shell between 53.8mm and 54.0mm I.D.
