Installed this on my 29er with disc brakes and the fit was perfect thanks to those adjustable leg positions. The aluminum tubing feels sturdy but it didn't add too much weight to the bike. My panniers clip on and stay put even on bumpy gravel roads.

The adjustable legs were a lifesaver for getting a perfect fit on my 29er with disc brakes. Installation was straightforward, though the included hardware could be slightly sturdier. For the price, it feels solid and does exactly what it needs to.
