Absolute Black XTR Asym 96BCD Oval Chainring: Shimano XTR asymmetrical 96BCD oval chainrings are designed for XTR 9000/9020 cranks that feature an asymmetric 96BCD. Oval rings help the rider spin smoother and generate more power. 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 1x9/10/11sp or Singlespeed setups. Designed in UK, manufactured in Poland.
