Hi all--I hope you don't mind if I jump in and ask a question. I've been lurking for awhile and really like this forum for its gentle camaraderie.

I recently built up a Salsa Casseroll, using a frameset I bought on ebay. I also got most of the components there (some used), primarily using Shimano 105.

I went with a nine-speed triple set up. But I've been thinking, I never, ever use the big ring on my crank, and I was wondering if a compact wouldn't be better for me. If I did change out the crankset for a compact, do I need to change everything else (brifters, rear and front derailleur, chain)?

Thanks!
