SHIMANO

First cassette lasted 2000 mi... At about 1800, things started getting wonky; miss shifts, skipping gears and getting very noisy...Got this new one and IMMEDIATE change! :) Instant on ALL shifts and completely silent again :) Worth every penny ;) I ride a lot, so, I go thru 2 MINIMUM per year :) Great value for an OEM part :)

Installation is easy IF you have the correct tools and you're handy. E-MTB burn through cassettes because of the high torque level of the motor. You shouldn't need a chain ring each year, but I bet you'll need a cassette each year. You'll know if your bike has "ghost skipping" but the derailleur is working fine. This model is one of the most durable because of material, but also less expensive than lighter drive train components. I'm not saying weight doesn't matter, BUT, with an E bike, do care about a few ounces? If so, keep scrolling. BUY A NEW CHAIN when you replace a cassette. You're welcome

Perfect fit for my aspect 970

Picked up this cassette on the cheap as my SLX was worn. It was easy to install and not much heavier than the SLX cassette it was replacing. Since it's all steel, it should last a long time.Shifts were much better after installing this and a new chain. After getting it all setup, I can hear the difference. Smoother and faster shifting with no missed shifts.

I pulled the xt cassette to throw this bulletproof all steel cassette on. I didn't need the weight saving as I'm primarily on the lowest gears tech climbing. It works great with an xt derailleur and I've put over 3k miles on, it still looks brand new after degrease.

Nothing to add, Shimano speaks for itself, I don't need to say how good the brand is.

I needed to replace my 11 speed cassett on my Electric YT Decoy and this was a perfect fit and I picked up some top speed with the 10 tooth (smallest) highest 12th speed sprocket on dirt trails, downhills and road rides!!! A++
