Bought both my Spesh Roubaix and Secteur Elite from the shop in Greenwich along with a lot of accessories, clothing etc. Always very good service. When I went over the bonnet of a car, they re-trued my front wheel and had a look of the bike to make sure ok free of charge.
If you are a member of LCC you will also get 10% disc off accessories.
The shop in Orpington is also ok. Had a spoke ping on an Easton a while back. They fixed that day for £9.00. They said all the spokes were a little overtightened so sorted that out and the wheel has remained true ever since.
So all in all a 2 thumbs fresh from me.
