Yeah dude, Pro 2 all the way, when you refer to the xoo hubs etc.. is that like the freehubs? As most of us know, steer well clear of anything Deng when it comes to freehubs, they may be revised for this year but all previous ones have been known to cause absolute chaos, they skip, crack, snap, fall apart, eat themselves, implode, everything! Iif you are a heavy rider, i'd gp for an echo rim, they're massively strong and come in plenty of nifty coulours aswell Matt
