Purchased for specialized Camber .up graded to 12 speed shifts good no issues. Buy new chain when replacing cassettes for issue free repcment.

this is a great option to finding a micro-spine hub. shifts just fine, opens the door to lots of wheelset choices

I don't know why people bitch about Sunrace cassettes--I've bought several over the years--they never fall apart, don't get loose, don't slip on the freehub body, don't drop chains and just do what they are expected to do---that's what you want, right? I will continue to use these cassettes on my builds

I purchased this as it was compatible with a Shimano Hyperglide (HG) hub. My bike has the older 135mm dropouts and I was skeptical that it would fit. When right on and mated with a Shimano SLX derailleur and shifter it works great.I had a 1x9 groupset previously and was unhappy with the large steps from one gear to the next, either one gear was too easy and the next gear down was more than I wanted. This cassette took care of that problem, I can always find a suitable gear for all riding conditions.

I have a mountain bike wheel with a HG driver from a previous bike that had a SRAM NX cassette, but I wanted to set that wheel up with a Shimano-compatible 12 speed cassette to go with the Shimano XT components that came on the new bike. An aftermarket cassette like this is the only way to do that without replacing the driver, so I decided to give it a try. Took a bit longer than normal to get the tuning just right but once I got it, the shift quality with this cassette seems just as good as if I had switched the driver and put an OEM Shimano cassette on it. A good option for anyone looking to go Shimano 12 speed on a Hyperglide driver.

Fit perfect. All black is a good look. Newer Shimano 12sp cassettes use a new spline pattern so this is perfect for a wheel with an older standard hub body. Chain moves great across all rings.This is on an older mountain bike I use for road riding so I’ll have to see about the life. My LBS sells them so I would say it’s a quality product based on that alone.

Upgrade from 9 speed cassette to this 12 speed cassette. Works great with shimano 12speed chain. Not so good with sram chain but I’m not sure if it’s my chain ring caused the issue.

Excellent cassette, shifting is perfect. Using with the regular old Deore 12s 6100.
