As is common with Eagle drives, a larger rear cassette also means a larger chainring in the front, which leads to less ground clearance. One advantage of the TRS+ cassette is that our 9-46t range achieves the same gearing but with a smaller front chainring and more ground clearance, which is even more important with today's "long, low, slack" bikes. The largest sprockets are precisely made from aluminum and are mounted on a SRAM XD driver body. The remaining eight steel sprockets are secured with a chain whip. Both parts of the TRS+ cassette are individually replaceable and sold separately, allowing worn parts to be replaced without having to buy a completely new cassette. More range, more fun, the same standard.
