Sizing for 1995 M400

[George Vollmer]

Hey everyone, what size do I need to be looking for. I am 5'11 and wear 30 inch pants. No idea how to gauge the frame sizes and haven't owned an M400 for 23 years. Any help appreciated.

I would guess a 20" would be right. Standover height on a 20" is 31.3" and the effective top tube length is 23.3" center to center, 23.8" actual. You might look around locally for other brands with similar dimensions that you can test ride and get a feel for the sizing. BWorks in STL has used bikes that you can test ride or rent. Don't know if there's a co-op on the IL side of the river.
