Using a CC-1

wrote in message ...

Maybe you could offer a hint of what you find exaggerated and why you
believe it is so. I don't see anything constructive in your shouting.


That you consider a chain worn out at 1/16" elongation over 12" Only a shop
mechanic with access to cheap chains and free time has a real reason to
think this way. 1/8" is considered the minimal 'stretch' at which to
replace.


Measure along the top run cranking to tension the chain. This
ensures chain is dead straight with excess lubricant displaced.
Remember the chain will be under great tension when riding.

I see you don't do this or you would have noticed that the front
derailleur and the right seat stay interfere with the measurement as
you suggest doing. What I suggest is a reasonable way of measuring
chain wear considering the nature of cosine error of small angles of
chain sag (1 deg) and that the chain never has any slack in it under
operation. Adding pedal tension does nothing to change chain length
unless you are thinking of forcing the pedal with several hundred
pounds of force. The we would be looking at elastic elongation, which
is not useful in determining chain wear.


Another technique you knock because you have not attempted it, or are you
just too awkward? It is a simple matter to place a ruler over the top of
the chain to measure it, or have you not got a standard engineers steel
rule. Rear mech. hangs from the gear hanger and so the ruler stands on top
of the chain without any difficulty. It seems you are too set in your ways
for intelligent discussion. By the way, standard dictionary terms apply to
hanging and standing, not Jobstian definitions.

Hey Trevor, could you answer my question -

What are your qualifications and credentials?
What is your background? What qualifies you to be giving advice, in
everything bicycle?

I'm serious, I would like to know.

Why bother replying to what was written when you can make something else
up?

Dear David,

Why bother sneering would you and Jobst could have tried
putting a ruler on the top run?

I did--it works fine.

Trevor's point about the rear derailleur, in all likelihood,
is that you can shove a yard stick in from the back of the
bike over the top chain run--there's nothing in the way.

Help me use my CC-1

I'm struggling to get reliable readings of chain wear
from my Park Tools CC-1 (the blue gadget with a moving
pin in one end).

What is the correct technique? Also I note that the pin
in one end seems slightly bent. Are they all like this
or has mine got damaged? Ta.

Correction, it's a CC-2.
