This works perfectly for the co-op bikes from REI as stock replacement parts. It does its job well.

Broke my hanger on a 10 year old like and needed a quick replacement. This arrived in a timely manner and fit, and works, perfectly. My bike shifts nicely and it seems as sturdy as any other after market option that I have seen; appears to be exactly the same as the OEM version

I bought this to replace a broken hanger from a crash. It fit well and bolted on with no problems. I have not seen any issues with it. We are not trying to win any races or slim down weight as much as possible. Seems good.

Had a crash the last weekend that bent the OEM hangar on my 2019 GT Aggressor Pro. Finding the correct hangar for bikes isn't the most straight forward task. After purchasing a hangar that was advertised for my bike that was machined so poorly that there was over a centimeter gap between the frame and the hangar, I did more research and came across this hangar that had legitimate part numbers that corresponded to the GT booklet of parts. This gave me confidence that this is the correct hangar.Only one day for shipping and being delivered, hangar installed within a couple of minutes and there was a HUGE difference in how smooth the drivetrain was shifting. A few more minutes of indexing the hangar, the bike was shifting better than ever.I recommend this brand and will be buying more from them in the future for my hangar needs.

Didn’t fit my GT aggressor but the build quality looks good. Be sure it fits I had to return it cause I lost the OEM and didn’t remember the shape of it.
