I'd like to get myself one of these tools. http://parktool.com/products/detail.asp?cat=4&item=FR-1
I have a double chainring on the front of my old schwinn that I converted to a single. I'd like to change it up a bit so I can use the bigger ring when I ride to work, then go back to the small ring when I want to do the mtb. I wonder if I should just put a front derailleur on and I can shift it whenever. I'm not sure how well that would work though. I wonder if it would bind too much. Any thoughts?
