John: I used this Shimano cluster to replace a brand-new SRAM cluster because the SRAM cluster kept letting the chain to slip/jump while in gear. The Shimano has worked flawlessly so far.

rocky96: Als Schaltwerk habe ich die Shimano Deore RD-M592 und meine Kette ist eine CN-HG71. Trotz Mittelmotor (ohne Schaltentlastung) sauberes Schalten, ohne Geräusche.

YesIAmAGeek: As I was replacing the chain as well, used the old chain to make up a chain whip, not too difficult (thank you, park tools video), and presto, done. Well, okay took me longer, but satisfying and saved some $$. Cost was not much more than a chain, and now shifts smoothly and reliably with now skipping. Best to replace all three--cassette, chain, and wheelset--together, if you can because one worn part will chew up the rest.

Forystt M.Forystt M.: Quick Notes:
- Great quality cassette that’s light in weight.(I didn’t put it on a scale but just holding it I could tell it weighs less than 1lb.)
- Easy to install you just need a chain whip or an old chain and some gloves (is what I use) and a Shimano freewheel remover to take off your old cassette and just the freewheel tool to install the new cassette.
- Can take a lot of force being applied to it without any chain slippage.
- Up shifting (high toothed gears) is as smooth as butter and has the smoothest down shifting (lower toothed gears) that I’ve experienced out of any cassette I’ve used.
- Becomes super shinny again when cleaned with simple degreaser.
- I would recommend this cassette to anyone looking to replace or just upgrade their current cassette.

Full Review:
I’ve used this cassette every day for 3 weeks now and have put a few hundred miles on if so far and I’m very pleased with its performance. I installed this cassette in less than ten minutes including setup. To replace a cassette you will need a chain whip and a Shimano Freewheel remover. It’s worth noting that if your cheap like I am you can just use an old chain and...
