UK readers: get to Selfridges.
Guys, of interest to the UK folk only. Wife and I went to Oxford St in London today, and had a look around the Cycle Surgery in the sports department (1st floor).
All I can say is wow! This has to be one of the most professionally designed bike centres you will ever set eyes on. Sure, they are very limited in the bikes they sell (no Cannondales or Kleins) for example! Seriously, they do sell some mighty fine equipment and they have a good choice of general stuff on offer. In fact, Selfridges has to have one of the best sports departments I've seen anywhere. They cate for just about everything. A bit like LL Bean in the US, but more compact.
If you ever near Selfridges, pop in have a look - it is really worth it!
