SRAM XX1 Eagle Cassette XG 1299 12 Speed Copper Bronze

A maximum strength-to-weight ratio is achieved with an X-Dome machined 10-cog structure. 10-52 spread equals or exceeds the range of heavier 2x drive trains.

Fits the same XD drivers that are used for SRAM 10-42 11-speed cassettes

The largest cog is aluminium

Tooth profiles provide better up-and-down shifting and improve chain retention

Titanium Nitride surface treatment reduces friction and enhances wear

The XG-1299 Eagle cassette meets durability requirements for E-MTB applications.
