    This is for (as always) some vintage bikes.

    Are the Kool stop Gray and/or White pads the same composition as
    the Orange ones

    No

    / or do the orange stop that much better (and

    Quoted message said:

    maybe wear better too) ?

    Yes.

    I've heard that the orange were orange due

    to the iron content... leading me to believe that color matters.

    As a side question... anyone know if the old weinmann "red" pads
    were red for the same reason ?

    No.

    Quoted message said:

    They always stopped and wore better
    than the black but I thought it was the "four block" design that
    did that - not the composition. Now I wonder though.

    I think it may have had more to do with the freshness of the rubber. It
    dries out over time.

    Thanks Sheldon. Is it my imagination or are the current kool stops a
    much brighter orange than the old Scott-Mathauser shoes?

    I don't think there's any difference, the Scotts you mostly see are
    older and dirtier.

    Quoted message said:

    Are the kool stop continental's still being manufactured or are they
    at "NOS" status now too ?

    As far as I know they're still in production. At least we don't have
    any trouble getting them.

  3. before i head over to NAPA
    for a can of belt dressing and a pack of razor blades
    let me ask:

    will the modern longer brake pads such as sold thru the harris
    website, longer than stock or oem circa l987 ten speed pads, cause
    dysfunction when mounted on the standard dia-compe 10 speed centerpull
    brake units?

    or recommend a max length for 10 speed centerpulls?
    does the max length vary with the compound?

    i had to ask before coughing up $25.
    the photos are just beautiful.

    - - No. I have KoolStop MTB pads on my Mafac Racers and they work
    great.

    Depending on fork/rim clearance, you may need to use a "thinline" model
    in the front. But why would you want to use anything but "Continentals" on
    a dia-compe brake?

    I'm afraid those will cause your brakes to work better. Worse yet, if
    you install teflon-lined housing and stainless machined cables, you
    might be afflicted with "dual pivotus superioris", a nasty problem
    that can cause spontaneous flight over the handlebars ... :-) :-)

    Really? I have some old (but new) Scott-Mathauser pads and they do seem
    to be a darker color than the new ones. They are still in their original
    bag.

    Longer or shorter pads have no effect on brake performance.

  9. Continentals? What is a Continental-roll and butter?
    Mafac Racers? Ditto! stainless machined cables?

    The idea I picked up was: a gross increase in the center pull pad's
    effectiveness in converting motion to friction/heat would cause the
    center pull mechanism to malfunction-the mechanism would overload and
    pull downward with the rim rotation, misalign and uh blow out the
    sidewall or tangle itself in the whatis…

    This is not probable when increasing pad surface area on a center pull
    brake mechanism??

  10. weel, i asked sheldon brown to cover that-how much brake pad area will
    a centerpull take if a...
    and prior i asked expert one and thru 7 and each time gotta
    mumblemumble.
    there's a liabilty problem here for getting larger than original pads
    tangled in the whatis? gee i asked eureka- mumblemumble.
