Here's what I'm wondering....I have a 6.5 mph TT that I created near my house. It is relatively flat with about 300ft of elevation. In any event, I am up to 18.7 mph and am hoping to hit 19 mph this year. About how much time can I save over that distance with a skin suit? Not sure anyone will even be able to guess but thought I'd ask. FWIW, I'd like to be able to hit that mark for my 72nd birthday in June. Maybe a bit optimistic. But, by September...maybe.
