I guess my question really is, if I switch to a 29er with regular tubes and tires I should be able to lower my tire pressure and my chance of pinch flatting, how much more do I gain by going with tubeless? Is it that big of an advantage and weight savings? The stats on the weight savings seem to be confilicting.Edited by mudfoot - 8/12/2009 at 02:21 pm GMT
the bigger contact patch with the 29er is longer and not wider meaning it only help for and aft traction not lateral. Same pressure, same tires 26 vs 29 you will still have as big of a chance of pinch flatting with tubes.
The biggest advantage off tubeless are this
- lower pressure with out almost any chance of pinch flatting.
- better grip due to lower pressure
- faster rolling due to lower pressure
- more supple ride due to lower pressure
and you also get faster rolling due to decreased friction due to no tube/tire rubbing as the the tire flexes over terrain.
