Ochain N is built for riders who want more calm, control, and confidence on rough terrain. Its active spider design lets the chainring rotate backward to reduce pedal feedback, chain movement, and trail noise, helping the bike feel smoother through braking, cornering, and fast descents. With internal adjustment options for various degrees of travel, it can be tuned to suit your setup and riding style while keeping performance consistent across the cassette. The latest version also adds stronger impact resistance and improved sealing for better durability in real MTB conditions.
