Mine above is set up single speed (with flip-flop hub so I can go fixed). It is an absolute pleasure to ride as I have it set up. It just feels great. And I bought it because a mate had one similar and he just said it was the best all-round bike he had (and he has lots of bikes). Mine feels very nippy, and (whilst you would not want to do it) actually feels like you could throw it around like a little mountain bike.

I suspect it would be more lke owning a bottom of the range diesel Volkswagen Golf and a top of the range Golf GTI. When you took the GTI (the AA Special) to get the groceries you would know you could have taken the diesel, but you wouldn't regret having taken the better car!
