I have found i traction roll less with the 2.4 wheels. Less sidewall flex. The sidewalls were folding over on our high bite track with 2.2 wheels.
Paul, I know you recycle your inserts. I do the same with my aka red. The dirt tech inserts are more stiff than AKA reds, correct? I was thinking about smoothies for SRS, but I am concerned about how long the break in process will take. I might ask Spencer the next time I see him, what his breaking procedure for the dirt tech inserts at SRS is.
