Headwind ======== Today I sort of repaired my old roadster bike. The single-speed Czechoslovak bike made by the Velamos company in the second half of the 20th century. It is well used and I already replaced many parts. The recent problem was the flat rear tyre. So I replaced the tube, re-seated everything and gave it a ride. But it was windy today. The side wind is not a problem, this heavy machine with rather wide 29" wheels (40-635) is very stable, But the headwind! I had to pull my bike to the hill as I was not able to climb against this wind. Riding downhill was possible but not really easy...
