The Sram XX SL Eagle chainring with T-Type technology is made of aluminum. It is dedicated to power measurement on the spider. It works perfectly with the chains, allowing smooth operation of the drivetrain and extending its lifespan. The special Narrow-Wide tooth profile firmly holds the chains, preventing them from falling off. The innovative threaded mounting method has allowed maximum weight reduction and significant improvement in the stiffness of the connection. It is compatible only with T-Type technology chains. Eagle Transmission technology redefines the drivetrain system on mountain bikes. The completely redesigned components are built around a universal fixed point – the wheel axle. This solution requires almost no adjustment while offering exceptional speed and precision even under maximum load. The mounting system of the modern derailleur significantly improves impact resistance without problems. T-Type components – those bearing this symbol – offer full compatibility among themselves, allowing mixing of individual parts between groups without concerns for performance and proper function.
