Hope Oval Retainer Ring 4-Arm 104mm Chainring Narrow-Wide - black

The oval Hope retainer chainring is CNC machined from 7075 T6 aluminium and hard anodized. With 4 mounting holes and 104mm BCD. It fits for 1x9/10/11-speed derailleur systems. Perfectly suited for trail riding, all mountain, enduro and downhill.

Ovality: The non-circular chainrings are intended to compensate the pulsating performance of the pedal movement in order to achieve a more smooth pedal stroke. For this, the Hope Oval Retainer Ring is equipped with an ovalization of 12 % at 113 degree clocking.

Narrow-Wide: Can be used with singlespeed, 1x9, 1x10 and 1x11 as it fits all chains. Tooth shape optimized for quiet work. The narrow-wide tooth profile virtually eliminates the risk of a dropped chain. No chainguide needed.
