AbsoluteBlack DM Cinch Oval "Boost" Chainring

Difference between Boost 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.

Fits Race Face cranks with the Cinch system
Boost version has 3mm offset
Oval rings help the rider spin smoother and generate more power
Example: 32t is equivalent to 30t at deadspot and 34t at the power zone
Narrow-wide tooth profile keeps the chain snug, allowing you to leave the chain guide behind
Works with 1x9/10/11/12sp or Singlespeed setups (Not for Shimano 12spd Hyperglide+ chain)
Designed in UK, manufactured in Poland
Ring Type: single (anti chain drop)
Mount: Cinch DM 3mm offset
Oval/Round: oval
