Dig that skip tooth sprocket, that thing is a mess but an easily recoverable one. For the right money it may be a damn fine deal, you are experienced enough to know what to pay so good luck and I hope you get it and save it before yet another hack buys it and makes it worse............... Minibikin' Chad has a set of Arco wheels for sale as do I but mine are not listed nor as good so if you want to replace that poor rear wheel he can help you.
