pedal pusher Posted May 7, 2010 Share What is the best is the best pressure to run on a 29er?On my 26' I found 2.2bar the best for dirt & would go to around 3.5 for the road.What do you guys suggest? Link to comment Share on other sites More sharing options...
philip.maree Posted May 7, 2010 Share It depends on the surface and preference. I run my tires at 2.0 bar when it's dry and 1.8 bar when it's wet and I need more traction. Link to comment Share on other sites More sharing options...
phemanderac Posted May 7, 2010 Share I clearly know sqaut about MTB tyre pressure - let alone 29-er MTB tyre pressure. I ride at almost 4 bar all the time. Link to comment Share on other sites More sharing options...
Eldron Posted May 7, 2010 Share I run a 29x2.1 tyre at 2.1 bar wet, dry, rocky, hilly, whatever... Link to comment Share on other sites More sharing options...

Tubeless you can run a lower pressure than tubed. Less the pressure the more the traction. At 4bar you will be flying as the rolling resistance should be less. But that being said, traction should be a bit of an issue. Link to comment Share on other sites More sharing options...
SteveS Posted May 7, 2010 Share Front 1.9, rear 2.1 bar Link to comment Share on other sites More sharing options...
SteveS Posted May 7, 2010 Share Riding your MTB with 4 bar in your tyres, the only flying you will be doing is over the handlebars. When I strated Mtb'ing after being a roadie I too pumped my tyres 4 bar and could never understand why I fell so often. Link to comment Share on other sites More sharing options...

On a 29er you can run lower than a 26er. I'm running my Fastrak 2.0's at 1.7bar front and back. In the epic over harsher terrain I used 2bar. I weigh 79kg Muuuuch nicer at lower pressure.

Thanks for the info. I am going to ride them at 2 bar this weekend and see what it feels like. I am 64kg's. Link to comment Share on other sites More sharing options...
