Comparing bike frames on-line

Here's a good site I just found. Compare bike x with bike y

So long as the bike you own (or are interested in) is on their database then it works. Unfortunately they don't have any Viscount.

But could be useful if you have a bike that works well for you , is on their database and then you'd like to compare with 'bike x' that you don't have in front of you with 'bike y'
