Hello, It's an SR400. Originally came with Shimano 105. I bought a huge Peugeot (64cm I think) and swapped the group. I think it's a 6400. when it gets light out I'll look. And throw up some pics too. I do well on the flats actually. It's the climbs where I get dropped. That's why I thought about trying to get some bigger cogs in the back. It's not that big of a deal actually. And when I think about it, I'm older and probably just kidding myself, and not in as good of shape as I think.

Anyway, thanks for all the ideas. I'll try some of them out.
