Our premium 1X Cannondale Hollowgram direct mount Round chainrings are designed for Hollowgram crank family. Compatible with old and newest models.
Our Cannondale Direct Mount round chainrings are designed with an offset that works best with Cannondale Ai-drivetrain (FSI). When used on non Ai / FSI Frames, our direct mount round has 3mm less offset than original, non-Ai Cannondale chainring/spider. So in order to achieve perfect chainline, you will need in this case, to change the spacers on the BB axle and move right side crank closer to the frame. This is an easy task and sets the crank in very good position in relation to the frame.
Chainline: 47-50mm (5.7mm offset). Chainline depends on the length of the axle you use and spacers configuration.
