classic proflex geometry

[boro92]

Hi all,

Thought I'd seek out some help.
I've search around but cannot find any geometry figures on proflexes.
Specifically, does anyone know the head tube/seat tube angles on these bikes?

I wonder if the frames were designed differently than the norm to compensate for the "reverse rake" of the Girvin forks. Would really love to know!

EDIT: just realized i posted in the wrong forum. if mods would prefer to move this thread, i'll understand! my apologies.

if you don't get an answer here, try here where member 'Colin' is pretty hot on this sort of thing.

Thanks for the tip
will try there if this is proving to be a great unknown!

Does this help? if you look in archive, theres a little bit on the back of the 1993 catalogue that may help (i know cos i have the original here on my desk) says head was 71, seat 73. offset liststed as 38mm but then in a little diagram it looks like a vector starts at 45.5 then goes back to 34.9 before going up. But you see what you think...

Ah, perfect!

Thank you...looks like standard oldschool xc geometry with the 71/73 (i guess "aggressive" by today's standards). 38 offset is interesting...
