tds, I use a Lezyne rechargeable bike light for night rides, and Surly Singlators for SS (but they thread into the rear derailleur hanger, and the Rad doesn't have one). You'll need to locate a tensioner that mounts on the chainstay (or elsewhere). There are some that appear to mount on the chainstay on ebay.
