Know before you buy
No, this specific model is engineered exclusively for Bosch Gen 4 motors. It will not fit other motor systems or standard non-electric cranksets.
Steel is significantly more durable and wear-resistant than aluminum, which is essential for handling the higher torque and power output of e-bike motors. This ensures the teeth maintain their shape and chain retention capabilities over a much longer lifespan.
Yes, this chainring is fully compatible with both 11-speed and 12-speed SRAM Eagle drivetrains. It is designed to work seamlessly with the specific chain profiles used in these systems.
The X-Sync 2 design uses a sharp, narrow tooth profile that interlocks deeply with the chain links. This creates a secure hold that prevents the chain from dropping, even when riding over rough, technical terrain.
Yes, they are highly effective in wet or muddy conditions. By providing a space for debris to escape, these recesses prevent mud buildup from pushing the chain off the teeth, ensuring consistent power transfer.
