to 36psi. Ready to hit Connector trail and Forest Hill Divide Loop the next morning. Off on the trail I go, the trail was in great shape, slightly loose in spots, but overall good. On the first climb I noticed a noise that made me look down as if I had a flat, It was that "grippy" sound. No flat ... just grip, Nice. Next a nice little downhill section,Hmmmm... feeling pretty good.. "pong!"the side knobs brush off a boulder but the rear end stayed true to the line, Very nice. almost no deflection. My old tires would bounce off those things. High speed corner and accel out,.... Again, very nice. Its like going from the old single pawl rear hubs to multi pawl hubs, I just seems to "hook up" faster. I swear the whole rear end just felt stiffer but the suspension was working better than ever! I set several PR's on the trail that day and I wasn't even trying to push. I was the most comfortable I have been on the bike ever sense I got it. I give these tires two thumbs up!
