BOSCH E-BIKE MOTOR DM DROP-STOP CHAINRING - SHIMANO HG+

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.

COMPATIBILITY

• Chainring is compatible with Bosch G4 drive systems


• Drivetrains: Drop-Stop ST suits 1x12 Shimano HG+ drivetrains only

DROP-STOP TECHNOLOGY

Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile delivers ultimate chain retention and mud shedding ability.

RECOMMENDATIONS

• We recommend the use of a clutch style rear derailleur for the best chain security.


• If you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper in addition to a clutch-type rear derailleur. Without these precautions, you may experience chaindrops and/or chainsuck.
