Bosch New 20T Direct Mount Chainring BDU2XX For eBike System Gen 2 Black
The Bosch New 20T Direct Mount Chainring BDU2XX for eBike System Gen 2 Black is engineered for Bosch mid‑drive units, offering a seamless, zero offset fit for Gen 2 systems. The 20‑tooth design optimizes cadence and power delivery, enhancing pedal feel from the first pedal stroke to long climbs.
With a direct mount interface, installation is straightforward and secure, reducing wobble and misalignment that can derail smooth shifting. The black finish provides a durable, low‑glare look that stays clean under daily riding conditions.
Ideal for riders who want predictable gearing during city commutes, technical climbs, or mixed terrain. The 20T ring balances acceleration and efficiency, helping you maintain momentum without overworking the motor or drivetrain.
Designed specifically for eBike systems and Gen 2 Bosch setups, this chainring pairs with compatible chain lines and front chainrings to preserve drivetrain alignment and chain retention across miles of riding.
