I have encountered 'Retro Techno'. Rides a steel-framed fixed, but has recorded every inch of the ride, and their power output, and their heart rate. Spends their downtime removing the GPS tracks from inside controls, before putting it all on Strava.
Seems to like Falafel And Houmous Wraps.
Strength; knows every inch of the route.
Weakness; will describe every inch of the route, with estimated power output and expected heart rate and predicted cadence. Tells everyone it's 78", but might flip it for 74" at the turn.
