The Wolf Tooth 104/64 BCD Chainring is an easy upgrade for riders updating older cranksets or moving to a 1x setup. With Wolf Tooth’s narrow wide tooth profile, it offers secure chain retention and smooth, quiet pedaling. Lightweight and durable, it brings modern drivetrain performance to classic 104/64 BCD 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.
