- 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
