Review on SHIMANO Altus Direct Mount 🚲 Rear Derailleur for Mountain Bikes - RDM310 by Satish Greener

Revainrating 5 out of 5

Sleek and precise

This rear derailleur is great value for the money. Sturdy metal construction and large pulleys. This even works with my MicroShift, which I wasn't sure about because Shimano can be sensitive when mixing brands. It shifts smoothly and quietly with precise movements. I am very satisfied and it was a great update. I've read reviews that said that until you get up and get past the Deore line, this Altus derailleur is the best, despite Shimano's superior Acera line. Keep in mind my chain was too short after the replacement as the pulleys are larger than most derailleurs. If you don't want to add additional links to the thread, you need to add a new thread during installation. Otherwise, you can put too much stress on the suspension in top gear.
