Im seriously considering the tubliss system on my bike. This being said I was wondering if any experienced tubliss users could tell me, are they good or bad or what not. Plus I use a hard compound rear tire, so whats the best psi, or no air at all? Also if running 0psi is a bad idea, I guess you need a plug kit on your person at all times? I dont know.... sounds like its a really good system but has sketchy negatives to it.
