This cassette allows 511% gear range for a one-by-eleven Shimano or Sram drivetrain compared to 420% for Sram’s XX1 and even less than that for most Shimano drivetrains (most are 381%). At Contender Bicycles we have built many bicycles up with the e*thirteen TRS Race 11 speed cassette and can vouch that it works perfectly with both Sram and Shimano components. The three largest cogs being machined from aluminum offers you less weight while the remaining eight cogs have been made from steel to ensure durability in all riding elements.
The e*thirteen TRS race cassette features and exclusive 9t cog allowing you to have more range without having to make the largest cog bigger making it a great option for any 1x drivetrain. Both the aluminum and steel clusters are sold separately making them easily replaceable if needs be.
