About inflation speed: are you finding the CO2 method is fast? I am carrying them this year so that I don't have to carry a pump on my regular rides, but never have used one.
I'll have to disagree on the the generalization of mini-pumps though. My mini-morph, with L handle and hose, will get a 1 1/8 in (32 mm) 27 in tire up to 95 w/o undue effort or time. 60-something strokes if I remember correctly, about 1 per second. That
is a long time compared to a floor pump, but for occasional and reliable use very satisfactory, especially in 40 deg weather or below. I used mine just yesterday to see that it still works, to top off my 25 (measured 27) mm at 80 / 90 quickly.
At 160 lbs that's a pretty firm ride for me. You are at 180, what width tires and pressure are you running?
