This bike was posted over a year ago for £500 but has been heavily reduced so I'm just giving a heads up to anyone who's in the market for a good quality road bike.
I bought this at £500 and after a year of riding it, I still love it. I've since upgraded some parts but the frame has been solid and I have had numerous comments on how good the bike looks aesthetically.
It has a composite fork, Shimano Tiagra front / rear derailleur and STI shifters. The chainset is FSA and has Tektro brakes. All in all decent quality components for a bike at this price.
Just to add, the bike was not fully assembled when I received it. Brake cables were not fully fitted/cut down and the gearing needed indexing. So you may need someone in the know to do this if you don't feel confident in doing it yourself.

Hope this helps someone.
