huh! I love it when that happens.........

I called my LBS (Calif. Pedaler in Danville) and told them "I'm going on a tour, bike is 52-42-30 w/ 12-25." And then asked what he suggested.

Well first he felt that my set up would probably be fine. But after pushing a little bit (explaining what a slug I will be with the trailer) - he suggested EXACTLY what Sarah had suggested: an XT derailer and a 34T cog. The amazing thing is he only spent about a minute thinking about it. But I was really happy to hear he confirmed what Sarah had suggested. He said it would be just over $200 w/ labor. How does this price sound to y'all?

I'll give Chris a call also, but Danville is so much closer than San Leandro..........
