BOSCH E-BIKE MOTOR DM DROP-STOP B CHAINRING

Wolf Tooth Bosch Gen 4 Direct Mount Chainring, Drop-Stop B

A direct mount chainring for Bosch Gen 4 e-bike motors, machined from 7075-T6 aluminium in Minnesota. Wolf Tooth's wide/narrow tooth profile holds the chain on and sheds mud, which is exactly what you want on an e-bike putting out this much torque.

Key Features

• Drop-Stop B tooth profile for 9, 10 and 11 speed chains, plus 12 speed SRAM Eagle, Flattop, Transmission (T-Type), KMC, Connex and Wippermann
• Wide side of the tooth spreads the load for longer chainring life
• Narrow side clears mud and debris to cut friction
• Alternating wide/narrow pattern prevents chain derailment
• 55 mm chainline

Specifications

• Fits Boost and Super Boost bikes with the Bosch Gen 4 motor
• Not compatible with Pivot bikes using the Superboost chainline
• Sizes: 32T (87 g) and 34T (95 g)
• Material: 7075-T6 aluminium
