ZRACE 11-Speed Cassette 11-25T Road MTB Compatible

ZRACE 11-Speed Cassette Compatibility and Ratio Selection

Five ratio options ranging from compact 11-25T to wide-range 11-36T configurations address every cycling discipline, whether you prioritize speed on flat roads or need climbing gearing for mountain terrain. Full compatibility with Shimano Ultegra and 105 components guarantees precise shifting indexed perfectly to your existing derailleur and brake lever setup. The ZRACE 11-Speed cassette integrates with either road drop-bar or mountain bike flat-bar drivetrains, providing flexibility for cyclists building multi-use bikes or maintaining separate race and trail machines. Precision tooth profiling ensures smooth, predictable shifts even during cadence changes or sudden acceleration demands on competitive climbs. Hard-anodized aluminum construction resists corrosion from sweat, rain, and road salt while maintaining rigidity through thousands of shifts across all eleven sprockets.
