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

• Fits the same XD drivers that are used for SRAM 10-42 11 speed cassettes
• Largest cog is aluminum
• 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
