Great Derailleur.
I ordered this for an old mountain bike I picked up in a thrift store. I ordered the 31.8 size because my bike has a 28.6 frame size. I also ordered a set of shim spacers and the derailleur works perfectly. It was easy to install and adjust, I just had to buy a chain breaker. This is probably their most budget friendly derailleur but for my old bike, it's all I needed. I love it.I also ordered another one before this. It was for a 34.9 frame. I also ordered a set of shims for this to but it didn't line up right with my smallest sprocket probably because of the larger size difference. Both were good.

My front derailleur broke
But this one won't work on my bike. I can use it on another. That's the beauty of having a lot of bikes. This is pretty nicely constructed. Maybe I could Mickey Mouse my bike to make this one work I can use it till I get the right derailleur. I only need the large gear. But when I shift into the small gears in the back it pulls off the large gear onto the smaller ones in the front. And I believe if I sit this just for the front large gear it'll stay in place and not cross chain. So that's what I'll do until I get a different style

Doesn't fit 34.9mm
It will not fit a 34.9 mm tube. Now I need to order and wait for a different one.

Cheap junk
Junk. Will not stay in place. Poorly built. Have had it on two different bikes and ready to send it to the trash.
