BOSCH E-BIKE MOTOR DM DROP-STOP B CHAINRING

The Wolf Tooth Direct Mount Chainrings for Bosch E-Bike Motors are compatible with all Boost and Super Boost bikes that use the Bosch Gen 4 E-Bike Motor. This continues the Wolf Tooth product line of Drop-Stop chainrings for e-bike motors. Direct Mount Chainrings for Bosch E-Bike Motors are machined with 7075-T6 aluminum at Wolf Tooth in Minnesota, USA.

• Drop-Stop technology: On Wolf Tooth’s patented wide/narrow chainring, the wide side of the tooth has maximum contact on the drive side which spreads the load and improves chainring life. The narrow side allows clearance for mud and debris which reduces friction.


• Alternating wide/narrow tooth pattern prevents chain derailment.
