absoluteBLACK Oval Boost 148 Cinch DM RaceFace Chainring 30T Green

Direct Mount Chainring Compatible With RaceFace Cinch System Cranks
This absoluteBLACK OVAL BOOST 148 CINCH DIRECT MOUNT CHAINRING FOR RACE FACE is designed for CINCH system RaceFace users to mount a chainring directly to the crank. With unique Patent Pending narrow-wide teeth profiles your chain will stay in place for a minimum of 12 months. If you have a 4-arm RF crank, look at the 104BCD Oval ring. It has 6mm offset.

Why Choose A Boost148
The difference between Boost148 and non-boost chainrings is in the offset/dish of the chainring itself only. You would use same crank in both boost and non-boost bikes, but chainring offset has to be different to accommodate chainstay clearance. Boost chainrings have only 3mm offset while non-boost ones 6mm.

Maximise The Power Of Your Pedal Strokes
A rider does not produce power evenly through their pedal strokes so this premium absoluteBLACK OVAL BOOST RACEFACE CINCH DM N/W CHAINRING is crucial for those who want to maximise the part of the stroke where power is produced and minimise resistance where it isn't. Try absoluteBLACK OVAL and never look back

Oval Chainrings Produce A Round Feel In Pedal Strokes
Oval rings make the spin cycle a lot smoother and are easier on legs while climbing. The fact is that a round chainring doesn't transfer torque to your rear wheel as smoothly as an Oval one. You will actually feel your stroke to be more "round" with an Oval shape than with a round chainring.
