Always loved going fast on bikes, especially down mountains or pacing behind trucks and buses, so I was wondering......my R20 has an 8 spd SA hub in 451 rims with a 48t chainring and a 25t rear gog, 8th gear is quite tall, what if I installed that spare 58t chainring I have and get a friend to pace me behind a car or motorbike, I wonder what speed I can achieve?
Don't worry about me not being able to turn the cranks with such high gearing, my best pacing speed behind a bus on a flat road is 78.5kmph and I needed more gear inches.
