## Description

10A RD X.3 BLACK

Review: Exactly as advertised. - Nice for the price. Exactly what it states.
Review: Cheap plastic, but works perfect. - I ordered the X3 derailleur as a cheap stopgap while I waited for the US postal service to deliver an X7 derailleur that got lost in the mail. The X3 works fantastically. Yes it is plastic. Yes the pulleys are not replaceable. Yes it's only $20. But if shifts extremely smooth and precise. I've since received and installed the X7 derailleur I originally ordered and I can't hardly tell the difference. The X7 is all aluminum (except for the cable routing hook/loop) and the pulleys are replaceable. The X7 may be just a hair quicker, but the shift action on the X3 is actually lighter since the spring is not as strong. If you're looking for something that will work well with SRAM shifters and rival the performance of the costlier stuff, but not quite as concerned about durability, this is a great product.Would not hesitate to use and intall another.

### ⭐⭐⭐⭐ Loose hanger screw, works tho.
*by N***N on May 12, 2025*

Good quality, been on my ebike misaligned for a year. Yesterday looked into actually installing it right. Still working. One thing that needs mentioned tho, the included screw which attaches to the hanger is too loose it has like a half mm of give perpendicular to the wheel which, I stuck some metal epoxy in there to fix it
