54cm centre of BB to the top of the seat tube - this http://www.bike.caloriesmadesimple.com/Zep/Specs.htm shows the geometry (it shows a 2002 model but I think my 2006 version is the same)
For sale - Airborne Zeppelin Titanium bike – it's spent most of the last couple of years in my garage so this is an opportunity for someone else to make better use of it than I am!
The frame is 54cm seat tube, 54cm top tube – I'm around 5'11” and it's perfect for me – with Easton EC70 forks...
