Best solution for Sram BB30/PF30 cranks with short spindle.
Spiderless (direct mount) chainrings allow for flawless single speed or Sram 1x9/10/11 drivetrain setup.
These chainrings save more than 150g over the regular spider and chainring combo. Reliable, extremely light, stiff and clean looking on the bike.
Always use a new chain with a new chainring. Optimized to ride in heavy mud thanks to specially designed chamfers.
