The pin that holds the mech cage in place fell out so i put a lolly pop stick through it instead. And that was a good 5 rides ago i think i need a new one! My front wheel is a 36 hole D321 on a 32 hole hub, and the rim has two drill holes going through just one wall. Built last summer with odd spokes only buckled now. Survived the comp at fort bill and many other rides. Alex
