The White Industries TSR 1X Chainring delivers reliable chain retention and efficient power transfer for modern 8–12-speed 1x drivetrains. We precision-machine every chainring in our Petaluma, California facility using premium aluminum. As a result, every chainring offers exceptional strength, durability, and long-lasting performance.

The TSR, which stands for Tall-Short-Ring, features a narrow-wide tooth profile that securely grips the chain. This design helps reduce chain drops on rough trails, gravel roads, and technical terrain. Therefore, it’s an excellent choice for mountain bikes, gravel bikes, cyclocross bikes, and adventure bikes. It is also fully compatible with singlespeed drivetrains.

For more than 30 years, White Industries has designed and manufactured precision bicycle components that combine performance, reliability, and craftsmanship. The TSR 1X Chainring continues that tradition with carefully engineered tooth profiles that deliver smooth pedaling and dependable chain retention on every ride.

Most chainrings are precision-machined from 7075-T6 aluminum, a material known for its outstanding strength-to-weight ratio. Meanwhile, 48T through 52T chainrings are machined from 6061-T6 aluminum. This material provides the additional strength and stiffness needed for larger chainring sizes.

Whether you’re racing, exploring new trails, or commuting every day, the White Industries TSR 1X Chainring is built to perform. It delivers quiet operation, dependable chain retention, and the premium American-made quality riders have trusted for decades.
