Direct Mount for Cannondale Hollowgram Cranks


This direct mount chainring will replace your existing spider/chainring on Cannondale Hollowgram SI & SISL cranks.Chainline is nominally 48 mm but will vary slightly depending on the crank axle length on your bike. Exact same chainline as the Cannondale XX1 spider. Actual offset from crank mounting face to tooth centerline is 9 mm
Chainrings feature our patent pending Drop-Stop tooth design and are made from 7075 Aluminum.
Use a 10 or 11 speed chain.  If using a 9 speed drivetrain, plan to use a 10 speed chain (it will shift fine), as the 9 speed chain fits too loosely on the ring.
