If you enjoy bargain-hunting or are looking for something that's hard to find in bike shops or the usual online retailers, eBay is the place to go.
But as well as wonderful and almost forgotten gems like those, eBay also has loads of sections where bike shops and bargain specialists clear out gear at (sometimes) knockdown prices. Some of these are online specialists, but many are sales outposts of proper bike shops like Deeside's well-known Graham Weigh Cycles.
You can find all of these eBay cycling shops here.
The range and level of discounts on offer varies between dealers, so a bit of digging and browsing is required, but we've found good deals on soft goods like bags and clothing, and consumables like chains and cassettes.

Somewhere along the line came the discovery that he could string a few words together, followed by the even more remarkable discovery that people were mug enough to pay for this rather than expecting him to do an honest day's work.

The inevitable 30-something MAMIL transition saw him shift to skinny tyres and these days he lives in Cambridge where the lack of hills is more than made up for by the headwinds.
