Not to start an idle discussion, but why are you pedaling at 37 mph? A good tuck will yield much more than your (or my) feeble horsepower at those speeds (with their associated air resistance).

During Paris-Brest-Paris, we spun out our 48 x 14 (with 650B wheels) at 43 km/h (27 mph). However, not one tandem passed us on any of the many downhills of the ride. They worked their big gears hard as we coasted by them, resting our legs for the next uphill. -- Jan Heine Editor/Publisher Vintage Bicycle Quarterly c/o Il Vecchio Bicycles 140 Lakeside Ave, Ste.
