Will the Bushnell fit my frame?

If you are the owner of a Cannondale, Co-motion, GT Ruckus, Santana* or Fisher* the answer is yes, you can upgrade to a Bushnell eccentric. For everyone else, the answer is probably.


If you are a frame builder looking to buy a bb shell to fit a Bushnell, contact Nova for steel and aluminum shells, or Da Vinci for stainless steel or titanium bb shells. Vist our ebb distrigutor page for contact info.

* We are now producing shims for fitting our Bushnell eccentric into Fisher, Santana, and just about any bike that it wouldn't fit before.

The Bushnell eccentric is designed to fit in a bottom bracket shell that has an internal diameter of 53.8mm to 54.0mm (or 2.120" to 2.125"), or can be shimmed to 55 and 57mm sizes for just $20.
