Eric Hjertberg, who knows more about wheels than the rest of the planet combined, told me that the combined frontal area of 36 spokes is more than the bicycle frame itself, plus the spokes are spinning through the air as the bike moves forward, further adding drag to our forward movement. Thus, "the point" of having less spokes is about aerodynamics, NOT weight.
As for ultralight tubes, any time saved because they are lighter and offer less rolling resistance is probably negligible, especially when compared to the time lost to the higher frequency of punctures they will provide. - Chris Kostman La Jolla, CA http://www.XO-1.org http://www.adventurecorps.com On Jun 14, 6:39 pm, Jim Thill - Hiawatha Cyclery <thill....@gmail.com> wrote: > The spoke count matters very little compared to the weight of the tire/ > tube/rim combination.
