great bike.. few question...
hi~ just bought used bike from my friend happen to be experienced downhill biker, salsa frame loaded with simano xtr component for hydaulic breake,shifter,rear derailler.. i'm pretty happy with what i get. but he told me it doesn't have front derailler,crankset is not simano xtr but Truvativ Stylo al 7050 tv Crankset with Single, unramped ring. if i add front derailler, upgrade to xtr crankset, is it going to make bike go faster, easier to ride?? do i have a lot of advantage if i do so??? as being new to moutain biking, help me out to get clear answer please~
