the last two years ive been riding my 2009 rockhopper pro (the lovely gold coloured one) ,which ive upgraded to mostly XT apart from the wheels which are mavic crosstrails from 2010 , I’ve now got myself a 2008 trek fuel ex8 , i’m going to transfer most of my xt from the rockhopper to the trek , can anyone tell me which is the better wheelset , my crosstrails or the bontrager race which are fitted as standard to the trek any advice would be appreciated
