Bicycle crankarms with the product number MTB Sram XX1 Eagle Direct Mount Boost Crankset Chainring. The new design of the X-Sync 2 Eagle chainrings resulted from the study of thousands of worn X-Sync chainrings by SRAM engineers under laboratory and real riding conditions. The goal is to improve the performance of the Eagle system in all conditions. The larger and angular shape of the teeth was created to perfectly fit with the new Eagle chain links, better hold the chain on the chainring, enhance crankset efficiency, reduce friction, quiet the drivetrain system, and slow down wear.

The chainrings are made of aluminum and are available in standard and Boost versions.

Technologies

• SRAM X-SYNC: Provides the highest level of performance, power transfer, and durability. The raised, rectangular teeth of SRAM X-SYNC chainrings engage earlier than traditional triangular teeth. The sharp and narrow profile, as well as the rounded edges, contribute to excellent guidance of the flexible chain.
• Designed for maximum drivetrain efficiency in difficult conditions such as mud. The chain pins are designed with technological clearance, allowing more space for mud to freely pass between the inner links and rollers.
• The SRAM X-SYNC technology, designed in Germany, is an integral part of the drivetrain systems with a single SRAM 1x chainring.
