>>1271932just from personal experience
back upwards I was able to reach 50 kph
back horizontal I could get to 60 kph
back down in perfect weather I was able to reach 70 kph
the cadence by itself was making the bike unstable
that and I started to catch up to cars on the corners
>Pantani-stylean extra saddle either on the top tube or rear pannier rack could make this more fun
along with brake levers that can be reached from a tucked position
