OCHAIN manufactures innovative active spiders and cranksets for mountain bikes and e-bikes, designed to reduce pedal kickback and improve suspension performance.
OCHAIN is a specialized cycling component manufacturer best known for its patented active spider technology. Designed for mountain bikes and e-MTBs, OCHAIN products are engineered to isolate the rider from pedal kickback, resulting in a smoother, more controlled ride. By allowing the chainring to rotate independently of the crank by a few degrees, the system enhances suspension performance, reduces drivetrain noise, and minimizes rider fatigue on technical descents.
The OCHAIN lineup includes active spiders and dedicated cranksets compatible with major motor systems such as Bosch, Brose, Shimano, and Fazua. Regular maintenance, including periodic elastomer replacement, is essential to keep the active spider performing at its best. OCHAIN is now a part of the SRAM family, bringing its revolutionary drivetrain technology to a wider audience of mountain biking enthusiasts.
