sapim cx ray might be the answer.<br /><br />Weight : 278g (64 x 260 mm) <br />Fatigue test / wheel revolutions : 3.500.000 <br />Strength on middle section : 1600N/mm²<br /><br />They may not be the lightest on the market a piece but they are light, and they are very strong this fact means that you can make a weel with the same strength with lesser spokes and so lesser weight. They also are aero spokes(which fit in normal hubs) so speed quality whats also important should be fine. <br /><br />For air resistance off a wheel the number of spokes and them beiing aero or not seems of considerable importance.<br /><br />I replaced the freewheel side of one of my wheels with this type of spoke a week or 3 ago looks nice, haven't tested them jet as roads are or wet or even flooded or else covered with salt this time of year over here. In this weather I prefer my old wheels and bike to get the beating.<br /><br />are available in silver and black but are pricy 1.5 euro(13.5 rand?) a spoke for silver another 25 cents(2 rands) more for the black ones <br /><br />www.sapim.be
