Thanks for the feedback, nice to know its gone down well, wasn't sure if i'd unwittingly unleash the wrath of the traditionalists!
In answer to a couple of the questions:
May I ask what bar you have on it?
Is it my imagination or is the seat post out of alignment with the seat tube?
The bar is a FSA K-Force Flat bar circa 2005/6, http://www.bikeradar.com/ROAD/gear/cate ... bar-17250/
As for the seatpost being skewiff, i think (hope) its just the picture, looks alright in the metal, and its a ridiculously long 420mm seatpost, i'm 6ft and its an 18" frame so should be fine!
No idea on the weight of the bike as unfortunately i don't have scales handy. I'm hoping it comes in at about 18lbs. With no front derailleur and one chainring, all the carbon bits and the 1.5" tyres it may even (optimistically)be less. It should be, that Tune saddle isn't all that comfy!
