OChain Active Spider N SRAM 3-Bolt Direct Mount 104 BCD - Black
OChain Active Spider N SRAM 3-Bolt Direct Mount 104 BCD - Black
Ochain N is the spider damper with internally adjustable travel for full-suspension mountain bikes, in the SRAM 3-bolt direct mount version.
Designed for everything from downhill to trail, Ochain N lets the chainring rotate backward, decoupling you from pedal feedback forces. You get a quieter bike with less chain turbulence and noise, more stability while braking and cornering, and more control on rough terrain. It starts at 9° of travel, and aftermarket 6° and 12° travel chips let you tune it to your terrain, riding and bike.
Because Ochain is mounted on the crankset, those degrees aren't multiplied by the gear jumps of a wide-range cassette, so performance stays consistent on trail and enduro bikes where pedalling efficiency is key. SRAM has re-engineered it for impact resistance, with enhanced sealing for better contamination resistance and longevity.
