I owned a singlecross, again in a 56 at 6 foot. Thought it was an exceptional bike, esp for the price. Lovely green colour. Are they £400 new or something like that? The wheels are fairly shyte, mind – you might need to do something with the rear after not too long.
Sold it because I wanted to do a lot of off-roading on it – trail centres etc. I was changing the chain rings that often it was getting ridiculous. Replaced it with a geared tricross sport – would have easily kept both but space is at a premium in my flat and the wife won't stand for bikes leaning up everywhere.
