The Sram XX Eagle disc with T-Type technology is made of aluminum. It is designed for electric bikes with Shimano Steps motors. It works perfectly with chains, allowing smooth gear shifting and extending its lifespan. The special Narrow-Wide tooth profile securely holds the chain links, preventing chain drops. Compatible only with T-Type technology chains. The Eagle Transmission technology revolutionizes gear operation on mountain bikes. The fully redesigned components are based on a universal constant—the wheel hub. This solution requires almost no adjustments while providing excellent speed and precision even under maximum load. The modern derailleur's forkless mounting system significantly improves impact resistance. Components bearing this T-Type symbol are fully compatible with each other, allowing mixing of individual parts between groups without concerns about performance or proper operation.
