Following the advice I'm going to go and have a look at the N2A and see what I think.
Having decided that I've been doing a bit of reading about the 52mm wheels and the general consensus on cycling forums is that they don't really add much but have the disadvantage of making you slower off the mark as well as being very susceptible to side winds.
Thanks cougie, planet x is on the scheme, as is giant. How do you find your N2A? My only reservation was that if it's a particularly aggressive bike then I might suffer on a longer ride...... presumably you use yours generally and not just for racing?
There is a massive flaw in the logic of buying a bike based on it being the one that is available rather than the one that suits you best
yeah - point taken - didn't mean that to sound as foolish as it must have read! But the point is how the heck am I meant to be able to choose one when clearly they are both good bikes for someone of my limited ability?!
