your tire shouldnt be dottomed out liek that purely from preloading it, even if u wer eto drop from that ledge your hopping onto, it could damage your rim and give u easy pinch flats, i ride trials and usually ride 20-25 psi, unless i plan on doing big drops the ni raise it a bit

 LOL I like the sign! uhm I would love to WATCH you ride, as I just am unable to do that... staright is fine but sidehop... I'm f-cked

 Not to be a dumbass, as I don't know anything about trials, but is your tire supposed to be that low?

 lol... I ride like, 10-12 psi in the rear, I'm preloading. So its bottomed out.

 its a sick pic tho, and 10-12 psi is still abit low for trials
