I gave my carbon fibre boardman road bike to these guys and asked for a service. I can honestly say that the bike was returned to me in a better state than when I first purchased it seven years ago from Halfords. The bike engineers in the Bicycle shop turned it around in three days and were absolutely ruthless in making sure every aspect of the bike's mechanics were working utterly smoothly. They also kept me informed of costs and timelines as they progressed. Totally recommend this place.
