Thanks for the information Morelock, I wont rushing to get some tubs than.
For my road bike I followed the procedure that Josh outlined on the marginal gains podcast which involves repeatedly lowering tire pressure until the rim hits on bumps or handling gets numb and I now run 70psi front and rear. I'm assuming that that would be way to low for the track, is their a similar process for the track or just kinda guess or use the 2/3 body-weight formula I saw on here somewhere or set and forget?
