HOPE Chainring Direct Mount Spiderless Retainer Ring Narrow-Wide Boost Oval 1-fold | black
The Hope Direct Mount chainring has special teeth with narrow and wide shape in the change, which prevent jumping off the chains reliably. In conjunction with a SRAM Type2 or Shimano Shadow + rear derailleur, which have a greatly increased bias of the cage, the chain is reliably held in position even without chain guide.
The oval HOPE Spiderless Boost chainring was specially developed for the HOPE crankset. Direct mount chainrings provide a clean drive setup for 1x9 / 11/11 or single speed configurations. The weight advantage of the Direct-Mount chainrings compared to chainring and Spider is about 40 grams. The elaborately chased chainrings by HOPE are extremely light and sturdy and ensure a clean look on your bike. Thanks to the specially designed cutouts, it is optimally suited for use even in heavy mud.
The oval chainrings are designed to balance the pulsating power of the pedaling movement, so you can accomplish a clean, rounder kick. HOPE has equipped the Retainer Oval Chainring with ovalization of 12% at 113 ° clocking.
These chainrings fit only the patented HOPE Spiderless Retainer System and are therefore only compatible with HOPE cranks .
