Have been using my old Trek 7500 for quite some time as a commutourer and it has no problem with long rides and the comfort level is really high.

I did a drop bar conversion since I have no love for flat bars and find the drop bars to be the most versatile and comfortable when you are putting down serious miles every day... had actually planned on doing some long tours on it until I fragged my back.

The '99 7500 has a geometry that is quite similar to a 520 (it has been mistaken for one on a few occasions) and is more roadish than some of the later hybrid offerings.

The only original parts are the frame and fork... everything else has been replaced and upgraded.
