New buyer, need advice?

I just started cycling around town and am starting to get into a little bit. I am riding a really cheap bike that was a gift from work. I am looking to buy a bike that I can use for training, hopefully working my way up to triathlons. I have been to the local shops and have been given two recommendations. The Trek 7.2 and the Specialized Crosstrail. Any advice would be appreciated. I already have sizing down and my budget is around $500.

These are both terrific bikes, but the Crosstrail is definitely dirt-oriented. Get the Crosstrail if you plan to play in the dirt on weekends or you live at the end of a two-mile dirt road. Get the 7.2 FX if you're planning to do most of your riding on pavement.

Also, be aware of the fit. The Crosstrail should be fitted like a mountain bike, while FXs should be fit somewhere between a mountain and a road bike. It's best to try before buying.

If you're considering the 7.2 FX, you might also want to look at the Specialized Sirrus--it's equipped just like the 7.2 but it has a lighter frame and a fit that is a bit more upright.

Thanks for your input. I definitely will be spending more time on the pavement then dirt. I plan on visiting my LBS this week to test ride the FX and now the Sirrus. Thanks.

How about this Diamondback Insight RS Bike for only $400 bucks. Perfect for long rides on a paved trail.
