Bosch G4 SX/CX Direct Mount Steel Chainring

What Our Gearhead® Experts Are Saying:

"I’ve installed this on a Gen 4 CX build that sees a lot of steep, technical climbing. The steel holds up to the torque, and the narrow-wide profile keeps the chain planted even when things get rough."

Full-power climbs and technical switchbacks put real strain on our drivetrain. The BOSCH G4 E-MTB Chainring is built to handle that load, delivering consistent engagement and dependable chain control when the motor and legs are both working hard.

Designed to mount directly to Bosch Gen 4 and 5 Performance Line CX and SX motors, it keeps the setup clean and streamlined. The tough steel construction resists wear under high torque, while the narrow-wide tooth profile ensures secure chain retention with SHI 12-speed compatibility. When the trail turns steep and the assist kicks in, we keep pedaling smoothly and confidently.
