I posted this under another thread i had started in the AM section, with no response, so I figured I'd post here...


I was looking over the geometry of the On One 456 S.S. and noticed a discrepancy between effective top tube lengths.

Unreal Cycle's claim of:

16" - 23"
18" - 23.5"

and www.On-One.co.uk 's claim of:

16" - 600mm, or 23.6"
18" - 609mm, or 23.9"

Does someone have any verification of either number set? Or, a bike to measure it on?

Thanks in advance!
