from what I've read about them I came to the conclusion that they are good for everyday riding and spirited riding. But if you ride hard, and ride on the track, they arent the rearsets you should have. I think somebody on this forum had theirs break on the track.
^^^ Pretty much this. I bought a set wanting a cheap set of adjustables, and after trying to install them (they're made of very light-weight aluminum) with my stupid monkey arms, I stripped a few of the pre drilled holes just while trying to apply loc-tite. Seriously, I wasn't even tearing the ass end out or anything, I thought I was being gentle.
So, re-drilled, tapped, and used different hardware for some of the holes, felt secure enough. Held my weight when bouncing on them just fine. Liked the fact that they didn't have rubber bushings, but, you get what you pay for.
After making sure everything was properly aligned and installed, the cheap, way too soft aluminum shift rod snapped at the front bearing. That was like, 500 miles. Spirited mixed with occasional commute. Slapped the stockers back on, and no problems ever since.
If I decide to get another set of aftermarket rearsets, I'm gonna do the smart bet and save up for a quality set. But, YMMV.
