I run V's on my echo pure(w/dx32) with a adapter like this. They give a person more leverage, but don't work so well with wide rims because the arms stick out to far. http://www.observedtrials.net/otn3/DSC03479.JPG Here is a thread from OTN about a guy using V's for the first time and loving them. http://www.observedtrials.net/vb/showthrea...8903#post390082 I ran maguras on my Pure and didn't have any problems with them but I always liked how simple V's are. I would never go back now, I love how they have so much holding power when my back tire is hanging on the edge of a ledge and in ever other situation.
