I recently tried converting my old 10 speed into a singlespeed (I've never done that before). After a lot of struggling trying to get my new bolt on skewers to hold the rear wheel on, I noticed that I think my vertical dropouts are bent on one side, as the bolt seems to grab on to only half of the dropout. Is there a cheap solution for this? Or am I better off selling this for parts and getting something new? I've heard rumors of things called C-shaped washers and knurled washers, but I don't know where to find them. Any help would greatly be appreciated. Thanks.
