STP? Sexually transmitted p.......?
Talk about old? I worked through out last summer to get into shape to hang with this group of riders ( I was the wippersnapper for years). By the end of spring time, I felt pretty strong riding a couple or three times a week. The same hills I used to big ring up now required little effort. It was doable until the ride got some speed in it during the race season, the wippersnappers turned on the gas on these hills on the way back to the finish. That was when I realized the lack of power I was able to generate.
At least the fixers riders will take a turn when you slow up to force them up front. Our down here will continue to slow up. That's when I shift on the up hill and grind it out until they are out of gear or blow up. some of those guys are pretty good and will say something, most are just a bunch of punks. I have to hand it to some of them, there are some very strong fixie riders out there.
