I’ve ridden with 150s and 170s. 150s, at least for me, are still tough
to get up many of the hills; 170s are a lot easier. That might be partly
my own development; now that I’ve been riding 170s for a while, I’m going
back to the 150s in preparation for the Monterey 24 hour race, and I’ll
probably be better at them than I was. However, my 29er is still not back
on the road, after a too-small tube detonated on inflation; I’m waiting for
a larger tube to get the thing back on the road (or the dirt).
)Also I should’ve reduced airpressure some. Little roots were hammering
)me pretty good.
I find that I can’t run much below 40psi before I start to bottom out.
If you weigh less than me you might be able to get away with it.
