Do you have a picture?
What are you doing with the old bike?
Most importantly, while your speed is awesome, keep in mind that new bikes come with magic that wears off after a while. You're going fast partly because you have a great new ride with a fantastic frame, but also because, well, because you have a great new bike, and you're impressed and inspired to work harder. The only way you can keep this going, to keep the magic from wearing off, is to keep riding your old bike. The new one will feel great by comparison every time you get on it, instead of starting to feel normal, because it's your bike.
