Let me preface this by saying I admittedly know nothing about bike maintenance or bike maintenance terms. However, I recently began to convert my old road bike which is an old, but in good shape 10 speed by American Rider (whoever that is). Anyway, is there any sort of home depot part I might be able to use to space my gear correctly? I know they sell cheap conversion kits online, but I'm impatient and cheap, very cheap. Any ideas?
