As common with Eagle drivetrains, a larger rear cassette also means a larger chainring up front, resulting in less ground clearance. An advantage of the TRS+ cassette is that our 9-46t range accomplishes the same gearing but with a smaller front chainring and more ground clearance, which is even more important on today's "long, low, slack" bikes. The largest cogs are precision machined from aluminum and attach to a SRAM XD driver body. The remaining eight steel cogs lock into place with a chain whip. Both parts of the TRS+ cassette are individually replaceable and available separately, allowing for the replacement of worn parts without the need to buy a whole new cassette. More range, more fun, same standard.
