    I bought this in a pinch, I needed a derailleur but didn't want to spend much money. This is a great derailleur for the low price and it exceeded my expectations.

      Comments about Shimano SLX RD-M662 Rear Derailleur:

      Wanted a value priced upgrade for my more basic long cage deore rear derailer on my fat bike and thought this might fit the bill. For the very low price paid this was a very significant upgrade. The deore worked ok but I had a lot of annoying chain slap that even had my riding buddy's asking what was up with my bike. I checked the numbers and ordered a medium cage in this slx hoping it would be better. I am 100% happy with this derailer, the shifts are fast and accurate and my drive train is now all but silent plus I dropped a few grams in the process.

              Very good derailleur for the money. Easy to install and has held up to a good amount of abuse over 2+ seasons.

                Replaced a very old 9-speed XTR derailleur with this more current SLX derailleur. The added Shadow clutch significantly reduced chain slap and help me move to a 1x9 setup without a chainstay. Weight and shifting is identical and worked perfectly with existing shifters.

                    A definite upgrade from the deore m591. Follow the instructions if you want an easy install. Kills chain slap and delivers positive shifting. Don't see getting a better derailer for my hybrid unless I go 10 speed.

                      Perfect for those looking for some performance but not wanting to shell out lots of money. Does it shift like XTR nope, like XT pretty close. For the avid MTBer its the perfect derailleur. You can smash this into a rock and destroy it and oh well there is a couple bucks out the door. It performs just as well as XT without the price tag. For those wanting XTR level performance here is the reality check, if you need XTR you aren't buying it its given to you. Don't buy based upon name this SLX derailleur will probably out perform any of your expectations.

                        Smooth, precise, quick-shifting action and it keeps the chain slap to a minimum. Experimenting with changing to a single chainring, and this shortcage RD is proving to be the ticket. Take care and follow the instructions, and the install will be painless.

                          Run the GS cage on a 2x9 squishy. Tension spring is firm so it keeps chain slap down to almost zero & it is tucked out of the way. I haven't been able to hit anything with it yet.
