Dylan Barie: Bought this for a project bike that I'm building on the cheap. I put this with a new single speed front and new chain. Shifts perfectly! Good price and quality.

Valerie Tigert: I installed this cassette on a 1000 watt mid motor ebike about a month ago and it worked great with the new chain and front chain wheel I installed at the same time. Today, it started to jump teeth in high gear and did it every time I was in high gear. Upon examining the drive train after today's ride, I found high gear has a 2 tooth section broken out of the gear and another tooth half missing. Looks like I need to buy a little higher quality cassette next time. I may need to spend a little more money instead of buying the cheap stuff. I realize this motor is a beast and this cassette was probably never designed to handle that kind of power.

R. BONE: I put this on my mountain bike to get the extra low great. I ride hard on advanced single track trails with hard climbs. I think it warped when I made a gearchange going under power going up a long steep hill. I switched back to my SRAM cassette even though the low great only has 36 teeth but it handled me abusive shifting for 2 years without any issues. I bought the cheap cassette to try it out for a season before spending hundreds on upgrading the whole group set. I've decided that I like the extra gear range but I'll need something strong so I'm actually going to try the prime 9 box 3 setup.

Mister dog: Si quieres tirar tu dinero en la basura, compra este. Ni hemos conducido la bicicleta 100 km o ha fallado. Después de dos citas con el taller decidimos en comprar uno de mejor calidad. Dinero perdido.

Pierre-Luc G: Was happy to receive it early for my gravel bike but straight out of the box I didn't feel like I was gonna install it finally. Took the cassette in my hand and the metal was so soft that I could bend it with no effort. There's no way that I will install this, will definitely return it and don't ride until I finally find a real and decent product.

Mark BullenMark Bullen: The media could not be loaded.  A further update: the seller has sent me a free replacement which they assure me will not wobble. I have yet to test it.
Well, I have to change my recommendation. After initially being pleased with this cassette I discovered it could not be tightened enough to secure it without significant wobble. See the video.

I installed this 11-32 on my Klein Stage Comp road bike to replace an SRAM 11-32 which had a very strange gear selection (11,13,15,17,20,23,26,32). Not only are the gears more evenly distributed but the shifting is much crisper and smoother and the cassette is quieter. Highly recommend this product.

jc1179: I bought a recumbent trike it's lowest gear wasn't low enough for my purposes towing/climbing. This one works great for me although it won't hit the highest gear. I do think my issue is with the wolf tooth adapter is not in exactly the same plane as the factory derailleur so the spring inside the derailleur isn't pulling tight enough to pull it on the lowest gear and be able to also travel to the higest gear. I think my solution is a proper long arm derailleur for a mountain bike.
