I am in the process of looking for my first road bike and have started testing a couple. I am looking for a bike that would be great for longer rides/centuries, but still quick on loops around the park. I am not looking to race.

I am 5'7", 150. Currently I am riding a 51 cm Specialized Sirrus Comp. It fits pretty well, so I think that is roughly the right size frame for me.

So far I have tested a Specialized Roubaix Comp and Serotta Fierte (steel). I wasn't crazy about the Specialized...it didn't feel very quick when I wanted to accelerate, and I didn't actually find it very comfortable. It was a 52, probably the right size, but I felt too stretched out on it (the stem may have just been too long for me). I didn't really like the handling either.

I really liked the Serotta. It was actually a 54, but the shop moved the seat forward to compensate...I think a 52 would still probably be better. Anyways, the Serotta was comfortable, felt much quicker than the Specialized, and handled very nicely.

I am planning on trying a Bianchi 928 this weekend.

Based on what I'm looking for, and what I've liked/not liked so far, I'm wondering if anyone can recommend any other bikes I should try while I am looking.

I'm hoping to spend around $2500, give or take. I am open to carbon, steel, or ti (if there are any decent ones in my price range). I am not interested in aluminum.

Thanks for you advice.

The Serotta would be a great bike! However, just for fun I might try a Lemond "Spine" bike. I think the Zurich would be in the price range.

The fit must not have been right on the Roubaix as it should be one of the more comfortable rides for someone that hasn't ridden a road bike before as it is a more compact frame that allows a more upright position when riding.
