Oh, and by the way, I've said this before but I will say it again:

Before you get carried away with the almost effortless performance of a prospective new bike (n+1), first try replacing the chain (and cogs if required) on your current ride, just so you'll have a good basis for comparison. You may even be so amazed at the vastly enhanced performance of you current bike with only a new chain that you will forget about blowing money on a new bike! I think most people have too many bikes anyway. But you can never have too many wheels.
