Highlights
Why we rate it
Direct mount for Hollowgram
Fits Cannondale Hollowgram Si, SiSL and SiSL2 cranksets directly, for a tidy single-ring setup.
Narrow-wide teeth
Alternating thick and thin teeth hold the chain securely on a 1x drivetrain, keeping noise down and reducing the risk of dropped chains.
CNC-machined 7075-T6
Milled from high-strength 7075-T6 aluminium and hard-anodised, so the ring resists knocks and wear and keeps its finish.
Best with a clutch mech
For the most secure 1x setup ALUGEAR recommend a clutch rear derailleur and a fresh chain fitted with the new ring.
