Haha - I ended up accidentally doing a few laps of regents yesterday evening in between a coffee with a mate, wasn't actually too difficult hovering around the 30kph mark!
I love wheel sucking roadies on my 2 speed. They get well narky. I just sitting and spin as they click through the gears trying to drop me. Then they blow and I just coast past..
Yep! Proper fun. Out of the saddle feels very weird, and the jump between gears is massive.
Just checked strava though, 4th fastest today on the bit of embankment west of Vauxhall Bridge and only 15 seconds slower than my roadie pb. Wtf?
