A friend of mine is moving to Hong Kong soon and has asked me to sell this for him.
Size is Small/X Small, I'll get him to measure it tonight to make sure, but looks around 49/50cm.
It's the same as this http://www.evanscycles.com/products/specialized/allez-elite-2010-road-bike-ec019407
and has had a new (Tiagra, I imagine) outer chainring, and cassette fitted. Very few miles, just to and from work, and rarely in poor weather.
Little to no wear on rims, everything's good.
I'm going to ask for £480
as that's ebayish price. If you're interested and want to make me an offer then feel free, as I said - my pricing might be way off.
Remember, you're funding a lovely man's new life in Hong Kong with his partner, so be as generous as you like.
