Subject: Simplex Multiplicator - does it help?
|
I know SImplex used to recommend these for their bar ends. Did it make
much difference? It looks like the amount of leverage gained would be
minimal and offset by the increase in "play" introduced by having
another mechanism in what would otherwise be a single cable.
But, I've never used one. Anyone have experience with one first hand,
maybe before and after?
Thanks,

Had one quite a while ago, left it out later, didn't seem to make any
difference

It's a demultiplicator. it's aim-so very French-was to decrease cable
pull at the derailleur, thereby increasing "feel" at the lever, or so
the ad I saw for it said. Nothing to do with streach or tandems or
anything ratiional. I had one-even made a braze-on for it-with Simplex
barends and it would pull a 7 speed freewheel just fine. I didn't
notice any increased feel but then, I'm not French. I still have one
floating around somewhere.

My understanding was that these things were primarily for tandems but used
on singles too when cables stretched more than they do today.
I asked a similar question a while back as I have some NOS Simplex shifters,
etc. Seem to remember that Sheldon Brown referenced them in his website
somewhere too.

Do not top post. I fixed it for you.
Cables do not stretch.
