Our premium 1X Cannondale Hollowgram direct mount narrow and wide oval chainrings are designed for the Hollowgram and FSA family of modular cranks. Compatible with old and new models. Climb faster, pedal easier, get oval.
Our Cannondale Direct Mount oval chainrings are designed with an offset that works best with the Cannondale Ai (FSI) drivetrain. When used on non-Ai/FSI frames, our direct mount oval has 3mm less offset than the original non-Ai Cannondale chainring/spider. So to achieve a perfect chainline, in this case you will need to change the spacers on the BB axle and move the right side crank closer to the frame. This is an easy task and puts the crank in a very good position in relation to the frame.
