what's the deal with nearly all pre built track wheelsets being 32h or 36h? It just seems weird that all pre built stuff is 32 or 36h, when they can handle cyclist my size, but I would think the norm is a much smaller person. Trying to buy a cheap wheelset for someone who weighs 105lbs right now and she definitely doesn't need the same spoke count as me, but is kinda stuck with it (it seems) unless she wants to really drop some $
