Wolf Tooth Direct Mount Chainrings for Bosch Gen. 4 E-Bike motors are compatible with all Boost and Super Boost bikes that use the Bosch Gen. 4 motor. This brings a lightweight chainring with patented Drop-Stop technology to e-bike chainrings for the first time. Direct Mount Chainrings for Bosch Gen 4 E-Bike Motors are machined with 7075-T6 aluminum at Wolf Tooth in Minnesota, USA.
This chainring is only compatible with Bosch Gen. 4 motor drive systems !
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. If using a 9-speed drivetrain, use a 10-speed chain. It fits tighter for better chain retention.
Compatible with all 9/10/11-speed chains and 12-speed chains of KMC, Connex, Wippermann, Campagnolo, SRAM Eagle, SRAM Transmission Flattop.
Not compatible with 12-speed Shimano Hyperglide+ and 13-speed Campagnolo chains !
