Well I went for a measure today

Some really nice bikes in there... I do like the Ridleys.
I got two measurements - one for Sport and one for Competition. The key points I think were:-
Sport: Saddle to BB 688mm; Seat Tube 506mm; Top Tube 531mm
Comp: Saddle to BB 692mm; Seat Tube 504mm; Top Tube 534mm
Comparing this with the Pinarello FP2: 51cm Seat Tube and a Top Tube of 537mm
This seems like a close match. I think :-s
Is it close enough I wonder...
