Erase pedal kickback and rewrite the rules of traction. The Ochain R active spider is a mechanical cheat code for gravity riders, engineered to let the chainring rotate backward and completely decouple your pedals from the harsh forces of suspension feedback. By actively isolating the transmission from the suspension kinematics, it drastically reduces chain turbulence and silences the bike. The result is a deeply planted ride that unlocks massive stability during heavy braking, aggressive cornering, and high-speed rock gardens.
Tuning your ride is now as simple as turning a 2.5mm hex key. The Ochain R’s patented EASY system features an external adjuster that lets you instantly toggle between Lock (0°), 4°, 6°, 9°, and 12° of float to perfectly match the track conditions. Because this isolation happens at the direct-mount crankset, these precise degrees are never distorted or multiplied by the wide gear ratios of your cassette. You get 100% consistent, predictable suspension performance whether you're grinding a steep liaison or sprinting to the finish line.
Crafted from premium 7075 T6 alloy, this latest R-generation architecture is the most bombproof iteration yet. Boasting re-engineered impact resistance and heavily fortified sealing to reject grit and moisture, it guarantees season-long durability and factory-fresh performance in the most hostile riding environments.
What's the difference between the R and the N?
Both devices have adjustable degrees of freedom. On the R it is external and can be adjusted between 0, 4, 6, 9 and 12 degrees. 0 degrees acts as a normal chainring would (meaning you can set it to have no effect on pedaling for long climbs) and 12 degrees gives you the most amount of kickback-deleting effect which gives the best downhill performance. On the N model, the degrees of freedom are also adjustable between 4, 6, 9 and 12, but this is done internally and requires the Ochain to be disassembled and rebuilt (about a 20 minute job in the workshop).
