Great shifting experience for an 11sp. Plenty of room for adjustments and has taken beatings quite well :)

Thank you Amazon for such quick shipping and such great price on such a great product. Broke my old derailleur on Saturday, ordered new derailleur on Sunday afternoon, and UPS delivered on Tuesday evening, Wednesday had the bike ready to ride again for only $80 bucks. If I would have taken my bike to a shop it would have been down for weeks and most likely had a bill in the hundreds $$$ ... show more

As advertised! Quick and simple installation on my 2019 Salsa Mukluk. Replaced the original Shimano SLX. Smooth and precise shifting.

Replaced an XTR that had a broken Cage.. The replacement cage cost as much as this derailleur. I personally can't tell the difference. Not sure about the durability! Shifts perfectly and set up a breeze. If you are Not a weight weeny or a racer this derailleur is perfect for the money!

I have these on two different bikes. The first time, that was my fault. I had an 11-52t cassette, was in 1st or 2nd gear, tried to force the wheel off with the chain in its normal position (clutch off), and the cage broke. If you have an older 10x135mm spacing and a large cassette, take the chain off the chainring first before trying to remove the wheel. Other bike (12x142), this rear derailleur worked great for about the first 400 miles...then the clutch lever just fell off, I have no idea how, didn't crash or anything. Then...I was in a smaller 26t chainring, upshifted to the top 50t gear, heard a weird grinding sound. Top of hill, manually switched to large 34t chainring to go back down. Chain will not stay on big chainring anymore, wants to jump to the smaller one, like the cage got bent or something. I'm assuming the cage went so far back that the chain touched itself and got caught on something around one of the pulleys and bent something internal. Moral of the story: with this derailleur, you can force the cage forward with the clutch off and it's OK, but DO NOT accidentally force the cage backwards when it's not supposed to do that. Then it will break, even if the clutch is off. Otherwise it's OK, not great, obviously a lot better than something like a 7-speed Tourney. But my $40 9-speed Deore has way more miles on it and zero problems on a 3rd bike. Just sayin'... ... show more

This is the best rear derailleur I have ever used. I have this derailleur on my fatbike, mountain bike, and even my road bike. But Shimano has got to get their act together and make a derailleur that will work for a road bike to be used as a 1x that can accommodate at least a 11x40 cassette. I'm not as experienced using SRAM components, but they are much further ahead when it comes to 1x gearing components. ... show more
