I have to admit that some aspects of the vintage road bicycle annoy me greatly. Pedals with traps and straps are not my favorite but they do the job...


Down tube shifters, in my opinion, are dangerous to use but they do the job...


But Old School seat posts and the saddle mount assembly = pooey stinko..!



Once installed and tightened up, a lot, they still tend to rotate and/or rock. What am I doing wrong, if anything, or is this the nature of the beast?
