From the Hive:
The TRS+ Cassette is all about range. Using a 2 piece assembly, we were able to offer a 9 tooth cog on the high end, and a 44 tooth(11sp) or 42 tooth (10sp) on the low end. The back assembly is machined from aluminum and includes either three or two gears depending on which speed setup you’re using. This locks onto a SRAM XD driver body. The remaining eight gears lock on using a chain whip. The front cluster is the same between both the 10- and 11-speed cassettes though the back cluster changes. We use a smaller cluster made from heat-treated steel which is then machined to achieve the lightest weight possible. Regardless of how strong our alloy parts are, they’ll wear faster that your steel assembly. That’s why we’re offering the aluminum cogs separately, so you can replace what’s needed without wasting perfectly good steel and money. Plus, the steel parts are identical for 10 and 11speed cassettes, so if you decide to upgrade your drivetrain, all you need to do is swap the aluminum assembly.
