Wolf Tooth Direct Mount Chainrings for Shimano E-Bike Motors have a 55mm chainline and are compatible with all Boost and Super Boost bikes that use the Shimano EP8, E8000, and E7000 e-bike motor splines.


Direct Mount Chainrings for Shimano E-Bike Motors are machined with 7075-T6 aluminum at Wolf Tooth in Minnesota, USA.


The Drop-Stop B tooth profile is compatible with almost all 9-, 10-, 11-, and 12-speed chains – the only exception is Shimano Hyperglide+.



  • 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



  • Compatible with all Boost and Super Boost bikes that use the Shimano EP8, E8000, and E7000 e-bike motors

  • 55mm chainline



  • Available in two different tooth profiles for optimal performance based on your chain type. tHE Drop-Stop B tooth profile is compatible with almost all 9-, 10-, 11-, and 12-speed chains – the only exception is Shimano Hyperglide+.



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.
