Ochain S power meter spider

The Ochain S spider power meter is an advanced device designed for electric mountain bikes (E-MTB) that enhances control and stability on challenging terrain.This power meter features an innovative spider design that allows the chainring to rotate backwards, decoupling the rider from pedal feedback forces. This reduces chain noise and turbulence, providing a quieter and smoother pedalling experience. Its external travel adjustment offers selectable movement degrees (lock, 3°, 6°, 9°, or 12°) to suit different riding styles and terrain types, improving stability when braking and cornering. It is specifically designed for compatibility with Bosch BDU38 (CX Gen 5) motors and 104bcd chainrings, and stands out for its enhanced resistance to impacts and contamination, ensuring durability and consistent performance.The Ochain S spider power meter also features a simple maintenance system, with elastomer replacement service every 100 hours and full service every 200 hours.
