Wolf Tooth 100 BCD Chainring for 3T Torno

Wolf Tooth 100 BCD Chainring for 3T Torno Info

Wolf Tooth 100 BCD Chainring for 3T Torno is a purpose-built 1x chainring engineered exclusively for the 3T Torno crankset and spider. Precision machined in Minnesota from high-strength 7075-T6 aluminum, this chainring is designed to integrate seamlessly with the Torno’s unique countersunk bolt pattern and spider interface for optimal power transfer.

Unlike standard 100 BCD rings, this model is custom-shaped to work specifically with the 3T Torno spider. The countersunk bolt design does more than secure the ring—it allows the ring’s shape to engage with the spider for improved stiffness and efficient power delivery under load.

At its core is Wolf Tooth’s proven Drop-Stop® wide/narrow tooth profile, developed for 1x drivetrains to maximize chain retention. The alternating wide/narrow teeth reduce the likelihood of chain derailment while promoting mud clearance and consistent engagement across rough terrain.
