I'm 6'2" and currently 255.My wheelsets are 1.handbuilt velocity V's to formulas with double butted in the back and straight gauge in the front 2.handbuilt open sport to formula with double butted 3.factory weinmann V's to formula with straight gauge(trued and tensioned at shop)and a cheapo 27" weinmann box rim to suzue jr set.All sets are 3X,except the velocity front(2X).The only set that needs occasional trueing is the 27" one,all the others are perfectly fine.I ride my bikes almost exclusively in the city with potholes and everything else that comes along with it and have yet to break a spoke(i might have jinxed myself now).
