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?
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.
Thanks for the words, chaps.
