I was talking about Cambridge bikes selection- they have a nice selection of bikes, lots of Chrome and MW product-which I don't see at all usually.

Superb did not have much junk when I was there. They had some aerospokes hanging from the rafters but most of the bikes were Superb and some other track/fixed as well as a lot of Linus bikes.
They had a decent selection of product, nothing like Cambridge, but ok.

My friend had his bike serviced and modified there and was happy.
I don't have any experience but the people that worked there were friendly and answered all our questions.

I find it hard to believe they wouldn't let a working cyclist change his tire out of the rain, that does not mix with what I saw.
But, if true, it certainly is offputting.
