While we may not be able to match your older model crank with an exact model we will support all Shimano Hollowtech II crank interfaces for road and mountain bikes.

Cannondale’s Hollowgram cranks all rely on the same bottom bracket attachment, which will only work with a Cannondale Hollowgram right crank arm; however, Cannondale changed their crank and BB designs during the 2013/2014 model year.  We support this new dimensions with our Cannondale Si version, which is compatible with Si 2014 version and all SiSL2 cranks.
