My 1 foray into DIY Frame building, I went off the norm, by making the top tube longer than the seat tube, 60/58,
so with mudguards on I avoided TCO.. having the wheel that wee bit ahead of my center of mass
did make the wheel feel lighter.
built in 1974~ish , still works ,
[I have A Pauls Flatbed Rack on the front, now..]
