the 7.5 is nice - i had a 7.7 and was in love with it. but riding only 60 miles a week almost doesn't justify spending that price for the bike. that's actually why i sold mine - bc i barely rode it. i recall doing a 45 mile ride on my 7.7 and i felt fine afterwards - no noticable pain or anything and that's what that bike is built for - comfort. i've done 20+ mile rides on my old 7.2 and my current 7.3 - either bike is perfect for rides that length.
