Dura ace EX bike(?)

[fritzlite]

just picked this one up.. frame has Columbus Thron stickers, and a Dura ace EX sticker...and shimano DA in the paint job, toptube..
BB is DA 7400, and headset DA handscrew...and wheelset, high flange DA(rear needs rapair..)

think i´ve seen this somewhere before, is it a shimano DA showbike, or ?
year?

cheers

I had something similar by Peugeot, Columbus Thron and similar cable guides

Looks like your bike has a mix of regular DA (hubs), DA EX (most), DA AX (drive side crank) and 7400

Also the graphics: The decal on the dt is the script from the 7400 ...and you say there is an EX decal as well.

Interesting is your cranks have a nice adapter unit to fit conventional pedals!

so it might be a peugeot?.. mine is lugged ...
yes, think its a mix.. havnt got the cranks, front(campy?) or rear derail or seatpost .. cranks look a little mod?

seattube has a sticker : shimano dura ace EX..
and one side on down tube: dura ace...

but think ive seen a pic online, of a shimano bike with dura ace parts.. ca 88-92?
