I've bought the Leonard Zinn book on eBay

Sometimes you can isolate noises by stressing each part as individually as possible.

For instance, standing next to the bike, squeezing both brakes, and the pedal at "3-oclock" step hard on the pedal, release, step hard again.

Repeat on the other side.


Also, when you notice it while riding, pay close attention to what type of effort causes it
I just performed your test! no doubt something is loose or wrong. A high pitched nock sound, only once as I move alternately from one side to the other. I can also feel the movement,,, the slack. Is there a way to tighten this up externally without taking the crank a part ? Just till I get the tools to do the job It's a very good test, thank you homebrew,

the threads b4 buying the tool(crank puller/extractor)

also noticed a Huret Jubile cable guide (the most elegant one ever)
Steve It is a Stronglight and late 70's father bought it in 1978. Important to know as to what tools I will need ? Mainly the extractor? The nice tools at a reasonable price recommended here in this post ,,by park tool seemed respected. I looked on eBay for others and the secondhand ones are about the same price as the new one why is that? Has the quality staid the same? So many things are going down in quality I could get an older one( extractor) as someone stated I could try using something good I have in the house , I have some good tool but I want the job to go as smoothly a possable for the pleasure of it, and not nicking up me or the bike . By the way are there other type of bike jobs one can complete with these same tools?

Next I am going to go non-cage and want very good bearing what do you recommend please, and how many ?


By for now , cheers.
