Comments about PRO Tharsis OS Mountain Stem:

I purchased this with a bike to bring the fit down to size for me. It didn't require a lot of tension on the bolts to get a snug fit (rated at 6Nm). It certainly has a unique look (as you can see in the picture) that might not be for everyone and there seems to be a lot of material there, so it might not be the lightest stem around. All in all, I enjoy it. Price is solid on Nashbar.

    Comments about PRO Tharsis OS Mountain Stem:

    I got this stem for my new Ellsworth full suspension tandem to replace the old style, long stem that was on the bike (probably a 120 mm stem). I wanted to bring the bike up-to-date, since I find (as do many aggressive mountain bikers), that I like the shorter stem with wider bar combination, plus the the Nashbar stem that was on there didn't seem well-made, and I don't want my stem failing.

    I am very pleased with this stem. It looks to be well made with good machining, and it was a GREAT deal. I spent only about a quarter of what equivalent stems usually cost. I believe this stem is built to last.
