I run a -10 stem so can't barspin without hitting the top tube but I reckon i would have clearance on the 38c's I have on there atm, I did crash the fork though and Its bent back slightly so barspins are doable with bigger tyres for me. I think this was barspinable when setup with 32c ribmos
You are riding brakeless with no foot retention, crashed - presumably because you couldn't stop in time, bent your forks and are still riding the same fork? Are you stupid or...?
