Are you running an eleven speed drivetrain but want more gearing than your current 10-42 tooth cassette? E* thirteen components have the solution to all your climbing problems!

A massive 511% range (11% more than eagle), light weight, fair price, and serviceable, all without a new 12 speed drivetrain. The 11 speed TRS Race cassette gets you 511% range, using your existing 11 speed drivetrain. The aluminum and steel clusters are sold separately as replacement parts. An industry exclusive 9t cog allows for more range without just making the big cog bigger. It also means you can run a smaller chainring than with competitor cassettes, allowing for greater ground clearance.The largest cogs are precision machined from aluminum and attach to a SRAM XD driver body with a lockring. The remaining eight steel cogs lock into place with a chain whip. Retail is $349 and they have just released a more affordable $249 version called the TRS+ cassette!
