Product Details

Does a mechanical advantage of increased gearing sound Interesting? If so read on.

Through research and testing of many different prototypes with varying amounts of Ovality we found 115% (from the top centre) to be the optimum.

This shrank the dead spot suitably and gave the same flawless chain retention and silence as our round rings. The shortening of the dead spot on the top and bottom of the power curve allows you to get back into the power phase of your crank rotation sooner.

All of our Chain Rings are + / -  2 Teeth so;

30T Has a combination of 32T Increased Power Phase and 28T Dead Spot

32T Has a combination of 34T  Increased Power Phase and 30T Dead Spot

Features

  • Thick Thin Tooth profile with Mud Bleed
  • 10 11 and 12 Speed Compatible
  • 115 Degree’s of Ovality
  • Fully CNC Machined from 7075 Aluminium
