Tech Tuesday

 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!

 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.

 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.

 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?

 hes changed loads since happy days

 Nice work Richard!

 lol im 120 lbs with a 2.35 and i have 40 psi

 so ok and how much Air Pressure to I need in my tire 24x2.7 n 26x2.7

 what was that blue bar on the bike?
