Thanks Rich and others. I just had a nice ~20 mile out and about (ending up at the grocery store 1 mile south of my house; the best kind of ride is a huge detour to a practical destination). I had put the fixed wheel back on it, the first time I've ridden the 48 X 17 fixed with the Naches Passes, and the bike felt very, very fast and smooth. Perhaps I'll keep the NPs on after all. Gearing is slightly higher at 72" than with the Elk Passes at 70", but the new frame seems to encourage torquing in a higher gear without bogging down or -- symptom I've experienced with other bikes with fixed drivetrains -- starting to cramp your quads after prolonged plugging away in slightly too high a gear.
I can't say that I feel any performance disadvantage with the Schwalbe SV 12 tubes (again, at 150 grams, over twice the weight as -- and with noticeably thicker walls than -- the SV 11 or whatever 26 X 1 / 650C X 23 skinnies). I may not bother to go tubeless. Curious: does anyone have experience with Specialized's "Airlock" sealant? This is a cheap, old-fashioned Slime type of sealant that I was told works better in tubes at lower pressures -- I was told it is "like Slime but better;" thus I've used it in the Naches Passes at 35-40 psi. So far, so good; no goathead flats; but I wonder how it works in tubes at higher pressures, like the 50-45 I use in the Elk Passes? It contains little wee fiber bits, I understand, in a substrate that is claimed not to evaporate the way Orange Seal or Stan's does -- glycol?. Has anyone used it and can he or she say? It's half the price of the "better" sealants. On Fri, Oct 16, 2020 at 9:47 AM RichS <rshannon6...@gmail.com> wrote: > Looks like it was well worth the effort Patrick.
