Shimano XT CS-M8000 Cassette Silver, 11-46

I bought this to drop the gearing on my 105-equiped 11 speed touring bike. With a Wolf Roadlink it worked straight away with a mid-length derailleur. If you fit 11 speed MTB cassettes to road hubs remember to fit a spacer as well - from memory 1.85 mm, but check online. Other hanger extenders are now available; if you google 'derailleur hanger extender' you should be able to find a perfectly good one for about £5.00. The roadlink is a lot more expensive. Suntour make one as well. I think they are both available on Amazon. Overall, a cheap way to adapt a road bike for touring and very easy to reverse.

Bought this for my gravel bike, brilliant quality as you’d expect and great for spinning up hills on a 2x system

The usual Shimano dependable engineering (upgraded from a SLX cassette as it's lighter). But they are expenensive for something that is ultimately going to wear out, hence only 4 stars.

It absolutely superb quality and smooth ride it fantastic, I love it. Thanks

great piece of kit lighter than the one i took off
