Do you have any info regarding bike check? Are participants supposed to send pictures or stuff is being tested regarding rules compliance at start line?
just turn up with pretty much any bike from any era and any style but it must have down tube or bar end shifters, external cable routing on the handlebar brake levers and toestrap style pedals. these are the only essential bits. i've seen people ride 10 speed wheels and even modern ti frames but they passed the other rules so all good to go
they check your bike on the start line and won't stamp your card if the bike doesn't adhere to those rules
