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.

Kong didn't survive this guy.
He had it for an hour.. We played tug for around 10 minutes then he took it off and chewed it up.. I thought Kongs were tougher to chew up.. very dissapointed.

One of the best dog toys we've found
This is one of my little girl's favorite toys. She's an aggressive chewer so at first we followed the manufacturers instructions not to let her use as a chew toy. It was purchased in January 2025, but it's holding up just fine. She likes to turn it into a pretzel for some reason, but hey it keeps her entertained! Highly recommend.

Good for play but don’t leave out to be chewed on
With two labs we need durable toys. This can stand up to the teeth when pulling but we can’t leave it laying around or it has chunks chewed out of it. And it’s not the toys fault that my girls can’t figure out how to each take a side, so it’s a human vs dog pull toy.

Toy is strong enough for a Rottweiler.
This is one of my dog’s favorite toys. He is a Rottweiler so I have to get him strong, sturdy toys. He hasn’t broken it yet!
