About Ebykr
Ebykr celebrates classic and vintage lightweight bicycles through provocative imagery and opinion. Ride along with us.
For almost 30 years Daniel Rebour drew the French bicycle for Le Cycle: numbered pen plates that showed readers how the best constructeurs built their machines. The man, his tandem, his pen and the gift that made his drawings worth keeping.
Campagnolo says its founder invented the quick release after a snowbound race in 1927 and patented it in 1930. The record tells a richer story: a first patent filed in May 1933, the cam quick release in April 1943, a parallelogram derailleur he perfected rather than invented, magnesium wheels for Lamborghini, a signed account of his life that never mentions the snow and a 1981 conviction that English-language histories leave out.
A dated timeline of Campagnolo from Tullio Campagnolo's birth in Vicenza in 1901 to the minority investment of 2026: his first patent of May 1933, the cam quick release of 1943, the Cambio Corsa and the Paris-Roubaix, the Gran Sport, Record and Super Record, magnesium wheels for Lamborghini, C-Record, Syncro and Ergopower, with the Croce d'Aune story marked as the legend it is.
A practical guide to dating vintage Campagnolo parts from the firm's own catalogs of about 1951 to 1986: when each model came and went, the changes you can measure on the part and what the numbers, the patent words and the address on a catalog or a box can tell you.
A practical guide to dating an Idéale saddle — why there is no date code, what the initials on the badge tell you, which models arrived when, how the alloy stamps and the rodée main mark narrow the window and how to date the paper.
A practical guide to identifying and dating Mafac brakes — why there is no date code to rely on, how the Racer's arm markings changed, which models arrived when and how to read Mafac's own three-digit lever code.
A practical guide to dating a vintage Fuji — finding and reading the serial number that carries its build month and year, telling the build year from the model year and confirming it all against the model, the decals, the components and the catalogs.
A practical guide to reading a Reynolds transfer — what each mark actually guarantees, how its small print and the tube it names date a frame and how to tell a respray from a reproduction, drawn from Reynolds' own literature of 1972 to 1990.
A practical guide to dating a Pierce bicycle from Buffalo — what the head badge says about who built it, why the first two digits are not the year, where a frame number sits on the ladder of dated examples, what the model numbers mean and which features arrived when.
