Right a bit of help. Ignore the question of getting Tri specific bike as s would confuse matters. I have a moderate bike (specialized 105 with cxp 22 wheels). The wheels are the obvious change to make to upgrade and gain speed (apart from training)! So for less than ??500 what do I get? I am moving next month to a flatter part of the country and would still use the cxp 22 for commuting and general training. Would I be better getting Mavic Kysrium Elites or a set of Planet X 50/50? I am aiming for them to be fairly all-round and not too extreme to get the most use. Am I perhaps missing the point?
