Rock Solid TRS+ series cassette offers an excellent range without the big jumps between those gears that you use the most. Having big steps in the cassette range can really disrupt cadence and flow on climbs. Because the e13 TRS+ uses a 9t lower cog, you can run a smaller front chainring, run less chain links - which loses weight slightly but improves clearance on the front and you don't lose out on top end speed. Although its approved for ebike usage its fine on normal bike and offers added durability. 10 steel cogs and 1 aluminium, no folding rings going on here - so if you punish your gear - steel is real. Who doesn't give a sh1t about the environment? You can replace worn out parts of the cassette without having to junk the whole unit when 1 sprocket is worn. 9-46T: 9-10-12-14-17-20-24-28-33-39-46 XD or XDR Driver Body compatible 12 speed compatible 390g Works with Shimano and SRAM drivetrains 10 steel + 1 Aluminium
