Hi there, I am relatively new to cycling (had to give up running) and I was thinking of 'upgrading' the piece of junk I currently have to something a little more serious. I was thinking of getting a second hand bike, basically looking for value for money, and noticed a couple of seemingly good bargins on ebay. One is a Ambrosio Celcius for £700 (new) and the other was a Colnago Dream Plus for £800. These prices represent my budget and seem pretty decent prices. Could some of you experts help to educate me as to whether these do actually represent good investments? Many thanks in advance.
