I just got back Monday from a three day 270 mile ride from Astoria, OR. to Bellingham, WA. I rode 128 miles the first day on a Brooks B-17 that had about 350 miles breakin on it. It has been pretty comfortable the whole time I have had it. My southern regions had some
soft tissue damage as the seatpost allowed the B-17 to slip back a bit and was just a little high in the front. Adjusting it forward a tad helped immensely
and I was able to do the next 142 miles with not much trouble. The advice to carry tools to adjust it on the fly were spot on. Its amazing what a difference a degree or two or a 1/4 inch will make!!
