I am posting here and in main forum. I believe there was an article about this topic but I can't seem to find it.
I currently ride an ancient 650 wheel TT bike. My road bike is also 650 wheels. I would like to replace the ancient 650 wheel TT bike but (of course) have found few manufacturers of these bikes. When it comes to the 650 wheel debate--I honestly don't know who to believe. Some people say 650 wheel bikes are slow and manufacturers stopped making them for this reason, some people say it doesn't matter (it's the engine), etc., etc.
Who do I believe? If I ride an extra small TT bike should I take a gander at an XS 700 wheel bike?
