I am saving up for a used small santa cruz bullit frame. I will do fr, dj, trails, wooden trails and some climbs. I don't want this bike to weigh a ton. I weigh about 120 lbs. I will get a marzzochi z150 fork. I will propably get a romic. What rims should get, I want mavic maybe 729. Would those be to heavy for my riding because i saw them on a v10? I want them to almost never need truing. Also what hubs should I get, I heard xt hubs are solid. I will get dt swiss spokes and nipples. I will get hayes hfx9 mag 8" discbrakes. I will get a titec el norte seat and a thomson seatpost. I will get truvativ husefelt cranks and a mrp lrp guide. Probably an lx derailer and an xtr front derailer. Can you help me with my bike I am saving up for?
