Where to buy lightweight tubes with short stems?
I can't seem to find any lightweight (say, 85 g or less) tubes for tires in the 26-32 mm width, 700C, with shortish stems -- 42 mm or shorter, prefer in the 30s. Anybody know of a reliable source? I could use about a half dozen.
FWIW, I found some at Universal Cycles: Michelin AirComp
But I appear to have bought out their stock of 30 mm stemmed tubes; the shortest they're showing now is 40 mm.
