We install Cannondale’s Hollowgram Crank System on nearly every bike we build. Historically, we stocked every single part, piece and replacement known to made, except for one: the elusive “Cannondale spindle spacers”. While these obviously came on your stock bike or as a piece packaged with a complete Hollowgram Bottom Bracket, these little gems were never available as a separate item to purchase.

To solve the problem, we custom CNC’d one for every road and mountain configuration possible. Even if your not installing this on a Cannondale, it will help you get a clean finished look with the exact proper spacing. They are lathed from 6061 aluminum, anodized in the same semi-matte finish as the Hollowgram arms, and then laser etched with the exact application and direction – right on the face. Use the table below to determine which spacers you need.
