I was reading on another thread that some or most or all (depending on who you ask) supercourses have strange proprietary threading on the BB's. Is there a way to find out which I have without taking it apart? Will either of the threadings found on a supercourse be impossible to find a newly manufactured replacement for for (not a big fan of ebay cruising, waiting for something to pop up)?
I have a '77, by the way.
Also, I was reading that some quill stems shouldn't be lowered too far because of a butted ...something (steerer tube?). I don't think this is an issue for my bike because when I had the stem out, I couldn't see an difference in diameter from the top to the bottom, but if it's the frame that's butted maybe I wouldn't see it unless I had the fork out of there, too.
There is a small spike inside of the fork's upper tube (sorry I am still learning proper names) that seems to be there, as far as I can figure, to keep the expander from dropping out the bottom. Is any of this correct?
Finally, can someone recommend the most inexpensive sturdy, compact chain tool they can think of?
Thanks again for all your help and patience, guys. I really went in over my head on this bike. I'm not a mechanic and I have no tools even after years of riding, because my bikes are super low maintenance, and I used to have a friend who was a mechanic. I sat and watched him replace my chain on my fixed gear, but I couldn't tell you the first thing about how to do it now. I guess you really only learn by doing something, which is a thing I used to tell my students when I was a math teacher, but forget occasionally, myself.
