You can ride what ever bike you want but will only be going as fast as the guy in front, me.
I have ridden this a few times, always fixed.
Once at 44x17 (69) with narrow bars - not so fun.
Once at 30x13 (62) with 38+35c tyres and wide bars - ideal.
Once pulling a trailer cycle with a junior rouler on board.
