Smooth. Works fine with 10sp cassette

By: Steve C on 16 July 2017
I bought a Shimano Altus RD-M310 derailleur to got with an 11-32 (10sp) rear cassette. I wanted to try the bigger jockey wheels (13t top & 15t bottom compared to usual 11t). It's much bigger than a 105 derailleur and about 80g heavier (total 300-320g) so it looks and feels a bit chunky but it's strong and I think it'll last forever. It's only meant for 7-8 speeds, but it works fine on the 10sp setup and is very smooth. The chain is a Shimano 105 CN-5701 Super Narrow HG 10 Sp chain, 110 links. Front gearset is 50-34. I'm very happy with the way it all works together.
