I disagree, everytime you replace the tires or tubes you have the chance to upgrade. But there is abig difference between choosing a replacement for a part that NEEDS to be replaced, and pulling parts off just for the sake of adding some bling bling. Nothing WRONG with doing that but from an economic standpoint, it's not the most frugal thing to do. Since not all bikes/wallets etc are equal, this person was simply asking for some feedback on their particular model.

But I think the question that started this thread is one most of us encounter as bike enthusiasts. Wondering how much better performance we can squeeze out of our steeds with that magic part or two. It's true we'd all do better to improve our own performance through diet, training, etc but at some point you have to consider your equipment too.

In some cases, a specific upgrade to a specific bike may very well NOT be worth doing. Even if you're Bill Gates, you might be better off getting a new bike if your goal is better performance. Even the world's richest dork can only ride one bike at a time.
