Review on ๐Ÿšฒ Shimano Deore RD-M591: 9-Speed Mountain Bike Rear Derailleur for Optimal Performance by Rodney Harris

Revainrating 5 out of 5

Excellent mid-range derailleur

I have no idea what clear means so no rating in this category but it is a good mid-range derailleur that works well with my 9 speed cassette is working. I broke my XTR derailleur but didn't want to spend money on such a quality replacement as I had an order for a new bike. It was just supposed to take time for the new bike to arrive and it has handled it well and I expect it will last a long time on my spare bike.

Pros
  • Good item
Cons
  • So far so good
