Thanks for the words, chaps.
Another dumb question...would an ultegra 11-speed double front mech work on my 105 10-speed set up? Surely there can't be that much variance between a 10-speed and 11-speed front mech?
And @chiroshi, what does this mean in terms of buying a headset?
Utter_Pleb-
Yeah it will be fine.

Hopefully not anything more than changing the crown race along with the rest of the headset as long as the fork steerer is a normal diameter. As someone else said, if you're not prepared to get out the calipers and measure everything, then I'd take it to a shop and get their advice.

Not a dumb question - and counter to other people, I'm not sure it will work. The new 11 speed front mech's have a totally different position for mounting and cable pull, so it might work, but will at best be sub-optimal. Better to get a band on adapter as others have suggested

But be careful with the race on the Spec forks. That bike probably had one of Specialized's 'Hiddenset's. Which means zero stack headset with caged ball bearings.
