Hey there! I currently have continental gatorskins 23mm on Mavic aksium race wheels and thinking of moving up to larger widths. My question is, for a lightweight rider, should I just switch to 25c and not bother about 28s, since I can run rather low PSIs alr due to my weight? Or would it be good to switch to 28mm tires. Just FYI, I have a 2010 TCR advacned 3, in size M/L.
