Today it was really nice weather, so I decided to do a tour with my street bike (Pinarello). After about 30 miles I had to climb up a long hill with a never ending straight part. Somewhere in the middle the Police installed a speed trap, they used a mobile Laser speedometer. When I came closer there was no other car on the road, so the measured me
They informed me - slightly amused - that I was at about 7 mph
That's just the same that my computer displayed - good to know that it's well adjusted ...
