Off topic, but if that was my Brooks, I would tighten up the adjuster a bit and apply some Proofide to increase water resistance.
Thanks for the heads-up, I did notice it had grown softer and more droopier that the much higher mileage Brook's B17 on my Voyageur but hadn't thought much of it.
again, I dont know if this is all in our heads
I can pretty much guarantee it isn't. Once a week, most weeks I ride with an evening "Social Ride" downtown, impromptu sprints on this ride are common. I unload the bike of all the panniers for this ride. When I sprinted a couple of weeks ago on the Voyageur I keenly felt the difference with the shorter cranks, and ironically I stood up in the saddle to try and make up the difference. Same bike this week, 5mm longer cranks, different ballgame.
The circumference of the circle described by the 175mm cranks is only about 3% longer than the 170mm crank, sure does feel different to me though.
