and roots and logs and where you need to hop or jump to get over some
things.
Consider the difference in going from an XC class tire to a 2.6" DH
class tire. It's about the same magnitude of difference when going
from a 2.6" DH class tire to a 3" DH class tire.
I don't really agree with this last statement. I rode the first two
days of CA MUni Weekend on a 26x3.0", and the last day on a 24x2.6",
including some of the same trail we'd done the day before. The 24 was
even set up with 150mm cranks instead of 170mm. Despite the fact that
it was my first day on that setup, I was able to ride pretty much all
the same stuff; loose gravel and scree was harder on the 2.6", but
manuvering through rock gardens and tight spots was easier. Since that
time, I've been riding the most technical terrain we have locally
(which gets quite technical) on the 2.6" setup, and I personally
perform at about the same level on either tire. I have actually gotten
up hills on the 2.6" that I never got up on the 3.0", probably because
of the reduced weight (not only of the tire, but of the whole setup).
I have also done quite a bit of XC riding, including riding a 29x2.1"
at Moab, and the difference between that setup and the 24x2.6" seems
much larger than the difference between the 2.6" and the 3.0". I'm
riding the 2.6" at Moab this year, and I don't expect to have any
difficulty doing things I could do before.
