DJR Posted November 8, 2019 Posted November 8, 2019 Talking about light steel bikes. This from an interview with Ernesto Colnago: Eddy Merckx hour record, 1972‘I built this bike for Eddy Merckx to attempt the Hour record on. At the time it was the lightest I had ever made, 5.75kg, and this was 46 years ago!‘The stem is titanium, and I had to send it to America to get it welded as no one in Europe knew how to weld titanium back then. ‘The spokes are titanium as well, and the hubs are made by Campagnolo from beryllium alloy, very light and stiff. ‘I drilled out every chain link by hand [saving 95g], which upset the chain’s makers, Regina Extra, as they said it would be too weak for Eddy’s power.’ Colnago also created an especially light headset – just 122g – and had a Columbus steel tubeset drawn that thinned to a mere 0.4mm wall-thickness in the middle, groundbreaking for the day. French company Clement provided 80g tubular tyres and Colnago redesigned a Cinelli Unicanitor saddle to have special sliding seat rails to achieve Merckx’s desired position. The bars were also Cinelli, again drilled out to save weight. Colnago says the fabrication alone took over 200 hours, but it was worth it. ‘I went to Mexico City [chosen for its high altitude and low air pressure] as Merckx’s mechanic. I was not that nervous, but Eddy was. Just five minutes before the start he asked to change the handlebars. ‘In the end he broke the record with 49.431km, and we got drunk together afterwards. It was one of the greatest days of my life.’ Just to make sure you don't miss what the important bit above is: A steel framed bike of 5,75kg was possible 46 years ago. Ok, I know it was a single speed stripped to its underpants, but still! Melo Joni, splat, pista and 1 other 4
