>From Mavic Timeline:

"1934 - A Duralumin dished rim, with a sort of 'tube' arrangement called eyelets carried the stress of the spokes on the lower and upper walls of the rim.

An Italian, Mario Longhi, perfected the same technique at precisely the same time and registered his patent on January 5, 1934–two hours before Mavic! The Italian allowed Mavic to exploit the procedure under license until 1947.

In the 1934 Tour de France, Antonin Magne tested these new rims in the utmost secrecy–they were banned by the rules, and so were painted in wood colors. Antonin Magne won the yellow jersey... Dura rims weighed 750 g compared with 1.2 kg for steel rims."

SoCal got a drenching rain all day today. First time in twenty years or so that the kids didn't get to ride their new bikes in the sun on Christmas day.
