I have a Canondale F7 that I kept at my mom's house in NC when I lived in California just to ride a couple times a year when I was visiting. Since moving back to the east coast that bike has just been sitting in the garage collecting dust.

Thinking of what to do with it and I'm considering a very basic/inexpensive single speed conversion. Nothing fancy, just something to ride around the neighborhood trails on with my kids. Thoughts?? Am I going to ruin an otherwise decent bike? And ballpark, about how cheap can I do this? sub $75'ish would be sweet! Anything else I might be missing please lemme know! I'm sure it will be a learning experience...

Thanks
Nick
