It's likely I'll get one or the other Surly eventually. That decision will then determine which of my current bikes I sell. Right now I'm leaning toward the CC for its versatility-which will likely edge out the Coda Sport.
If putting 25 cm tires on the Dolce will make a noticeable difference in the handling I'll certainly consider it, as the bike is a joy to ride-on decent roads. (Thank you to those who shared their personal experience of a relatively minor tire width change. It helps to know this could be an improvement in that area.)
I'm in my late 50s; breakneck speeds are not something I'm striving for at this stage of life...mainly looking for overall comfort for the occasional long ride. I do want to have more than one bike for different situations, and 30-50 miles will be a goal as my fitness improves. I'm overweight-but in good health. Bicycling has proven to be a great exercise choice for me.
A rear rack is somewhat important when considering the new bike; I often like to carry a few extra things. I know the CC is up for that task (and more!), but it does help to hear what others have done with these two models.
