Hopefully one that won't have me calling 911 and reporting a crime. Used is fine, just needs to work. 50t is OK. I have a bike I am trying to finish for my son, in hopes of keeping him riding instead of looking at cars/insurance I really can't afford. I do have a 12speed HG cassette I could trade as well (or partially). I can not for the life of me find the right end cap/freehub combo to make my wheels work with the HG. Project has taken *WAY* to long, just want it done, or finished to sell it off.

Thanks for any help.
