absoluteBLACK Oval 1x Cannondale Direct Mount Chainring Green 34T

1X Cannondale Hollowgram Compatible
absoluteBLACKs Cannondale Direct Mount oval chainrings are designed with an offset that works best with Cannondale Ai-drivetrain (FSI). When used on non Ai / FSI Frames, the direct mount oval has 3mm less offset than original, non-Ai Cannondale chainring/spider. 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.
