Were these like the current sizes or more like the Saluki and Bleriot, RAM sizing?

Thanks

More like the other frames of the era. You weren't getting super high headtubes and super long effective toptubes relative to the seatpost length, they used numbers closer to traditional road bike sizing.

This is what I had seen on the wayback machine from the old Riv website:

Rider Height: Mixte Size 
Up to 5' 5": 50
5' 6" to 5' 10": 56
5' 10" to 6' 3": 60

Thanks Joe, so more like the Saluki and Ram of the era. I have a 54 Saluki and a 51 Hillborne that are basically the same as far as clearance for me. TTs are a bit different.

Ii was 5'7" when I started riding again in '97, with back surgeries and age I have lost 2 inches, but that is not from below the waist so sizing becomes a bit confusing. My arms have the same reach but my upper body is 2" less than it was. I can still ride my 51 Hillborne and 54 Saluki and the fit seems fine.

Another few data points on Wilbury/Glorius frames: they also came in size 52. (We have two 52s.) See the attached PDF with excerpts from Rivendell Reader no. 19 from 2007 discussing the models. It has a handy chart that shows frame sizes and PBH for the Wilbury/Glorius Mixte, Atlantis, A. Homer Hillsen, and Saluki/Bleriot frames. It makes it easy to compare frame sizes and PBH. I highlighted the relevant section in red.

Jim, thank you, the chart is very helpful. I think it would be a bit different for the Betty or Gomez.

Wondering if anyone knows the effective TT length of a 56cm Wilbury?

Thanks
