realskiers

I would ask their pros before blindly following some website. ask any legit pro XC race guy there pressure and I be surprised to ever hear over 35 most are closer to 20-25. if it wasnt faster they wouldnt do it.

Agreed, And you/they have the engine to expend going fast.
For me, faster isn't much of a factor or motivation at all.  The legit "pro race guy" doesn't have any relevance to me.
That would be like me using the same skis that you use -- I don't ski the places that you go and don't place the same demands on my skis, or expect the same performance that you do.   


So the question becomes, for the average rider more than 40 years old (and his family), are tubeless MTB tires simpler, more cost effective, less tiring, and more reliable than tube type tires.
