 he looks kinda baked. Great video, psi is often overlooked by many.i dont know why, its so simple to do, like he said its free, and can make the difference between winning a race or walking down the trail

 For anyone DH racing. When I went under the 32psi, I DEFINITLY saw an difference in how the whole bike reacted to the ground. So go out and try different pressure for every type of conditions there is. You while find you sweet spot. Don't do like I did before, run 40psi because I didn't want any flat. haha!

 Hey, so I am 175 pounds, and have in the front a 24x3, and in the rear a 24x2.8. I ride PG&E service roads, and Freeride. we don't have any berms and most of the trail is dry dirt with rocks embedded in the ground. What pressure should I be running?

 This was really interesting, the one thing that wasn't discussed I was hoping to hear about was speed in relation to pressure. I've been under the impression for XC the higher the pressure the faster the bike, so long as you can control it and its within the limits. So for races I've always gone 43ish on 2.1-2.25 wheels, unless its really technical. will running lower reduce friction and increase speed? and do I want to reduce friction, because thats what pushes the bike??? so confused, I'll probably play around with my pressures this summer more.

 you said pinch flats dont matter in a tubeless... which is true
BUT tubeless tires can get run-flats when being used at low pressures (run flat means being run at an extremely low pressure, destroying the interior of the sidewall making the tire dangerous to use)
I work at a tire shop, and we get run-flats from car, weelbarrow, dirtbike, etc. tires even if they arent completely flat, and i am sure this is the same with bike tires.

 so ok and how much Air Pressure to I need in my tire 24x2.7 n 26x2.7
  • + 1
 Depends what the trail is like your riding mate, there is no correct or incorrect air pressure! - Tech Tuesday recommend roughly 32+ PSI if you watched the video...
