Hi

I don't think decent prices really apply or maybe the UK is really cheap! Migros sell some basic stuff competitively such as tyres and tubes.

Velomarkt is popular for both private selling and buying. The link is:

Another site is:

Veloplus have a workshop in their stores where anyone can make use of their tools if you don't want to buy tools. The shop has slightly higher prices to compensate for this.

A link to Swiss races is:

Thanks simoni for all the links. It's much appreciated.
