Reputable Bike Shops-Berkshire or Surrey Co., UK

[Tiny Tim]

Have been a distance runner since age 18 until the onset of osteo 6 years ago in both hips and now the subsequent bilateral hip "resurfacing" done on both of them last November (with great success).

Now looking into road biking to replace high-impact distance running and need to find a reputable shop in Berkshire or Surrey Co, maybe Middlesex, and any on-road bike clubs in either of the first 2 counties (preferably in the Windsor-Sunningdale area).

Thanks for any help.
