Absolute Black Cannondale Hollowgram DM Oval Ring
  • Oval rings help the rider to spin smoother and more efficiently
  • Example: 32t is equivalent to 30t at dead spot and 34t at the power zone
  • Replaces the existing chainring and spider on Cannondale Hollowgram cranks
  • Narrow-wide tooth profile keeps the chain snug, allowing you to leave the chain guide behind
  • Not for Shimano 12spd Hyperglide+ chain
  • Designed in UK, manufactured in Poland
  • AI8000 and up has updated design
