This is my single speed conversion I have been riding lately. I didn't have the desire to ride fixed so I just did a simple conversion to a freehub rear wheel. I am getting pretty addicted to riding single speed and it is not as grueling on the hills we have around here as I expected. Being 46 I feel pretty good to be able to do a 30 mile ride on this and be comfortable. Plus it is great on the Western Md. Rail Trail that is local to me. Great thread!
