Near as the Google will tell me this is OEM from a Cannondale Super V. Bought in haste, to be sold at leisure. Can't verify that it works but it was sold to me as working and looks to be in very good nick. 145mm/5.75" i2i overall length 165mm. Spring (Fox 850#-150) has a bit of bark off (see pics) but looks to be fine otherwise. Shock body looks good, a view tiny nicks on the decals but for a shock that came off the Ark it's in decent nick.
No idea really on pricing but 40 of your fine British pounds will see it sent to you via economy airmail. If you want it sent EMS fine but it'll be 10 pounds extra. In my experience economy airmail is fine and it rarely takes the 2 weeks they say it will. But your choice. PP gift if you don't mind.
Edited to add- E50 anywhere in the eurozone, $60 (US/Aust/Canada) NZ$70.
Happy to entertain swaps as well but please remember whatever you swap will need to be sent to Japan. If you have a rear disc brake you'll get my immediate attention. Also a rear shock 165mm i2i (sheepish grin).
