After doing a couple of days of RAGBRAI in 2011 I'm in for the whole week this year. I rode last year on my late 70s Miyata touring bike which is currently set up for commuting with expanded gearing and a taller handle bar stem for a more relaxed ride. I like the drop handlebars but my back doesn't handle an aggressive racing geometry bike well anymore. I've already made a tentative decision about the bike I'm going to get for next years ride, a Salsa Casseroll. But, before I plunk down my money I thought I'd give the opinionated in the group (you know who you are) a chance to weigh in. Thoughts?
