Hi AJ,

There are a few things going on with the cable issue...this is what I
understand to be the case:

Historically, there was a time when brake light switches were not
required for the front brake...only for the rear brake. I believe the
loop frames straddled this era, leaving original examples of front brake
cables with and without the brake light switch.

The original cables were made a of thicker diameter cable that was wound
differently than some of the cable available today. It is said that
original cables are less likely to stretch than some of the thinner
aftermarket cables. This gives a more direct link to the brakes and a
stiffer feel at the lever.

To add trouble with the mix, the brake light switch adds additional
mushy-ness to the equation. The old switches worked by compressing very
dense rubber (if I remember right) whereas the new switches work by
compressing springs. The old switchs feel firmer, if I'm not mistaken.

To get the most direct link to the front brakes, you'll want to use a
thick cable without any switches. But, you pay the price of not having
the rear brake light come on when this happens.

On my Ambo, I'm using an original cable with the original switch. The
switch didn't initially work, but only required disassembly and clean up
to get it going again (it's pretty simple). I'm happy with this
compromise as I don't want to always have to remember to use the rear
brake to activate the brake light.

There really isn't a clear "best" choice, but I hope I've unmuddied the
waters a bit.

I'm curious and ignorant. My bike has new cables from the PO and he told
me
that the front cable did not activate the brake light. So I am assuming
an
after market cable of some type with no switch. I would think that
having
the brake activate the brake light is important. Maybe I'm wrong? I see
that MG Cycle has replacement cables with a switch. Is this what I would

want or is there another work around.
