Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

believe it or not.. track riders dont really care about looks so much.. it has to do with building a stiffer wheel

I knew it had something to do with stiffness. My front wheel [high flange] is considerably stiffer than the rear.

tech aside... youre right.. high flange on a track bike just look way cooler.. just the way it is

It is true that higher flanges equal higher stiffness, as the expense of reliability of the wheel. Some superhigh flange hubs break spokes alot, I can't remember the name of the hub though, it's not a common one.
Tying and soldering spokes increases stiffness as well. Mr. Brandt does not approve of that, though.

shorter spokes are less elastic!

edit- actually i need to word that differently, i was imprecise. shorter spokes have less toal linear expansion given the same elasticity coefficient compared to a longer spoke. the result is a slightly stiffer wheel.

from the great sheldon...

""High-flange" or "large-flange" hubs have a larger flange, usually drilled out for lightness. They transmit torsional forces with less stress to the spokes than small-flange hubs do, but this is not a problem in practice with modern equipment. High-flange hubs can make a wheel with slightly greater lateral strength than equivalent small-flange hubs, because the spokes create a wider bracing angle to the rim. This makes them popular with track sprinters, who create greater-than-normal side loads on their wheels."
