Maximum strength-to-weight ratio is achieved with X-Dome machined 10-cog structure. 10-50 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
