Good job Enzo!
Folks who don't race track underestimate it. I get "all you do is ride around in circles" all the time from my roadie friends.
The ones who have come to race with me found it to be really eye opening! A few loved it and stuck with it, most see how hard it is and never come back.
I'm glad you're enjoying the racing! Keep at it, the experience you get will not only make you a better track racer, it will make you better at all cycling disciplines!
As far as tires, I've ben running Tufo. I think they're 22's. I race at T-Town and they hold up well on the concrete track. I raced them at the Lexus Velodrome and they worked well on their wood track, too.
I weigh 180 and run about 160psi. I tried the Vittorias and found they flat too easily. They're fast, but not so much when there's no air in them...
I've never used anything wider than a 23 on the track, but a buddy runs 25's and hasn't had problems.
It's great to read about your race experiences! Keep them coming!
