Compatible with SRAM XD and XDR driver bodies, this cassette integrates seamlessly with Shimano, SRAM, and TRP 12-speed drivetrains, offering broad cross-compatibility. The bronze finish not only provides a stylish aesthetic but also adds corrosion resistance for longevity. The lightweight design results in just 392 grams, so you can ride faster and more efficiently.

Style & Use Case:

Ideal for mountain biking, gravel adventures, and e-bike riding, the ethirteen Helix Race Cassette combines robust functionality with a sleek bronze style. Its versatile gear range makes it perfect for tackling steep climbs, fast descents, and technical terrain, giving you the confidence to push your limits.
