Any trialsin folks out there know the bead seat diameter of a 19" (sometimes called 20 x 2.50") rear trials tire? Maxxis says 387mm, Monty says 396mm, and another source told me 382mm. No help to be found from the usual oracles (Howard Sutherland, Sheldon Brown) on this one. Does anyone have a trials tire laying around with the ISO size molded into the sidewall?
Thanks,
Patrick
