SunRace MX3 Mountain Bike Bicycle Compatible with Shimano 10 Speed Cassette 11-40T or 42T

Fantastic item. Works perfectly with a Shimano SLX mech, KMC Chain and a Narrow/Wide chainring. I was hesitant about converingt to a 1 x 10spd wide ratio set up. I shouldn't have been - it's fantastic. Trail riding is so much smoother and more fun without the hassle of switching between 3 front chainrings and shifting your way through all the redundant gear combinations. As soon as funds allow I will be getting another one of these for one of my other bikes. Build quality is excellent and the red anodised parts look very nice indeed. Don't know how long it's going to last, but functionally it's excellent at the moment and much, much cheaper than similar items from other manufacturers - so replacing it when it wears out won't be scary. Highly recommended

This cassette works fine and gives a great range. However the provided lock ring is junk and will not stay in place. Its come undone 3x on me now, and the final time I'd tightened it up to the point where I though I was going to break the freewheel. Gone back to my Shimano cassette and no problems again.

I was a little sceptical as to if this would work with my setup. Very easy to fit, same as Shimano. The only adjustment needed was to turn the B screw in all the way. I'm running an XT 2x 10, XT Long cage rear with a blackspire chain tensioner. Took it out today and hit a couple of good technical hills, and this operated flawlessly. I would defiantly recommend.

Item was exactly as described and delivery was very prompt.

Had this for 2 years. Lasted really well and still going strong.Upgraded from a 36T to this 40T. Lasted longer than the original SRAM.Really well made. Easy to fit.Fitted to an electric bike, So impressed by how long its lasted despite the extra forces on it.With hindsight, should have gone for the 42T version, for even more vertical ascents!!!
