Review: Great Shimano Quality - Works as expected - great Shimano rear derailleur. My previous one did get damaged (bent) on a mountain bike ride - my fault. Was an easy swap out and needed only little adjustment. Shows that even a little bit of bend in the rear derailleur affects the shifting - now perfect shifting again. So - if your shifting is giving you trouble check the derailleur for potential damage and/or if your shifter cable is starting to fail.
Review: Nice upgrade to my original XT. - Great upgrade from the standard XT. I had to replace mine when a good size branch levered up off the trail while riding, wedged itself between the mech and the wheel and ripped the old XT off. This one was not much more than a direct replacement and the clutch is well worth the added price. I was used to having a chain drop or two on every ride (15-30+ miles). I've been riding with the shadow system for about 150 miles now and haven't had a drop the whole time! Slap is lessened or non existent... hard to tell when going through the really rough stuff but overall the chain is obviously much more stable. I can't see a reason to step back to a non shadow system if I had to replace this one. If you don't like it, you can just switch the little lever off!

### ⭐⭐⭐⭐⭐ Saved my 2024 Oak Mountain XTerra Triathlon
*by S***L on October 1, 2024*

Old derailleur died on my '18 Trek ProCaliber while pre-riding Oak Mountain, nobody had a 10-speed in stock anywhere in Shelby County but thanks to Cahaba Cycle I was able to order this from Amazon, it shipped promptly, and they installed it the day before the race. Worked perfectly and saved my race!
