Excellent value and performance.
Was having a bit of trouble with my GX Eagle ghost shifting and not staying in gear. I replaced the cassette with this SLX and used a XT chain with a Sram eagle quick link. Kept the Eagle shifter, derailleur, and absolute black oval chainring. Solved all my problems plus better shifting under power. The only negative is shifting to the smaller cog is a bit delayed or at least not as quick as shifting up to the larger cogs.
super smooth, nicely machined
i’m on my second slx cassette 2000 miles in and it’s been nothing short of incredible. i dont take great care of my drivetrain - never swapped chains and i only lube every third-ish ride or every other wash. i demoed a bike with a full gx setup and although it looked a bit cooler, it didn’t shift as nicely and silently. really like how you can just buy the individual sprockets for the first five gears. i’ll be taking care of this second one though. might look into garbaruk next as i’m becoming slightly more weight conscious (~250g savings). 10/10
Shifts as good as XT
Unless you’re a weight fanatic, there is no reason to buy the more expensive XT cassette.
