WORST BRAKES EVER!!! I had a set of those on my cross country bike in the early 90's and they didn't stop worth crap. I had the head mechanic at the shop I worked at adjust them and they still worked like crap.

True story: I entered in a cross country mtb race at Big Bear that was 21 miles of gradual climbing and 5 miles of rocky downhill to the finish. Between the bumps and the constant gripping of my crappy Avid Tri Align brakes, my finger muscles actually gave out and released the brake levers, launching me into the rear tire of the guy in front of me and making me fall into a rock. I switched to V brakes the next week.
