Probably a cable, does your speedo needle move smoothly or like it's on a rubber band? If it's the latter it's got a cable, first thing is to check it's tightened enough at both ends, if yes and still not working then it might be the actual cable is knackered. Try asking on some Vauxhall or Corsa forums as the geeks on their might know of an easy fix to a know fault that a dealer wouldn't admit to.

Carbon Fibre isn't really a great material for bicycle's, it's ok for pro's but personally i find them too stiff and unforgiving. Titanium all the way for me, not cheap crap tough, something nice from Dean, Ibis, Merlin or Litespeed would be great.
Mate, if your using it to get from A to B then i'd sell it as it will get nicked, very nice bike and the frame and rear shock are worth £1k on their own!
It doesn't seem very likely to me that it would take from Saturday night until monday morning before you were ill if the oysters were to blame, any reaction to food poisoning is usually within 6 hours not nearer 30!
