thanks for the help, also question why would a aluminum aero bar as oppose to a carbon bar of the same model be better?? Do you mean like the brackets dont work well on carbon but better on aluminum?? Like what i mean is Why would gettin the T2+cobra aeros bards be better than getting the cabron version?? Other they they are allot cheaper heh. Also yes i would like to get some weight off, thanks for the tip on the tires, I dont think i will switch out the wheelset, i like how dependable and strong this wheelset is. Hasnt needed to be brought into the LBS yet. As for getting a new crank that will now be happening as i see the teeth on this crank are not holding up heh. Is the Dura-Ace really stronger?? Like in terms of material strangth?
