Folk,
http://www.vintage-trek.com/images/trek/84Trek_23.jpg shows something I remember but have never
understood.
The geometry table references frame sizes in inches, but the seat tube lengths are measured in cm.
The confounding piece is that, when running the measures through english -> metric conversion
factors, the numbers clearly don't correspond.
In other words, Trek said that a 22.5" bicycle had a seat tube lenght of 56.0 cm.
22.5" * 2.54 = 51.15 cm
Can anyone explain this?
Thanks, Lin
