Wolf Tooth Trek TQ Direct Mount Chainring

Wolf Tooth Direct Mount Chainrings for TQ E-Bike Motors are compatible with all Boost and Super Boost bikes that use the TQ Motor. This brings a lightweight chainring with patented Drop-Stop® technology to e-bike chainrings for the first time. Direct Mount Chainrings for TQ E-Bike Motors are machined with 7075-T6 aluminum at Wolf Tooth in Minnesota, USA.

Drop-Stop B

Tooth shape is nearly identical to Drop-Stop A, but has narrower teeth. Valley between teeth is deeper to accommodate larger rollers on Flattop chain. Outside faces of narrow and wide teeth touch chain to guide alignment.

Drop-Stop ST

Narrower teeth than Drop-Stop A. Wide teeth use Symmetric Trapezoidal (ST) profile to match extended inner edge on chain to create alignment (outside faces of wide teeth do not touch). Interaction of narrow teeth and chain are similar to Drop-Stop A and B.
