Checked the scale today. Several "hangings" after each other. Used a carefully measured liter of water and it came in a gram under a kilo every time. That eases my mind about the scale.

Here is my 1971 Masi/Ferretti/Monark (ex Pettersson bike). It is a 59 c/c frame, with 28 spoke wheels and a lot of drilling done here and there. It also has Cobra/Omas ergal parts for the rear derailleur and crankarms. Pista pedals. It is set up as a time trial bike. Steel pedal and bottom bracket axles. As found apart from sliding the saddle a tad forward, taking off the spare tube under the saddle and removing the Campagnolo pump "umbrella".






Note - drilled handlebar.
