2010 Sunday Model-C 24

I've been having some on and off lower back issues and I've been trying out alternatives to 20" bikes (which I have been riding for 20+ years). I recently got a 26" Volume (and then Standard) that I loved and they got me interested in the Model C. I thought it might be the perfect middle ground. This bike is a lot of fun so far. I'll still be doing longer rides on my 26" but I have a feeling that this could replace my 20"...for the most part... maybe.
