cable routing, rollamajig?

futrino said:

Hi, I have and older (1995) fisher mountain bike with the rear deraileur
cable that runs along the top tube, then down the seat stays. The
cable housing has to bend in a way that makes a sharp angle. I have
tried to lengthen the housing, but it doesn't help much and it can't
stick out to far, off road riding, off trail excursions etc. I tried a
rollamajig, it worked until it broke. I have a newer xt mega-nine
derailer. Shifting the rapidfire, the thumb lever is stiff and both
down and upshifts are slow.

Question: can I use something other than a plastic rollamajig, like
those V-brake adapters or some other pulley system?

Or I know I once saw a metal rollamajig, but can't find it anymore.

thanks, dan

I saw something about using a V-brake noodle. I will try tonight.

JTek Shiftmate - any model. It uses bilevel reduction pulley to alter
the cable pull so you can mix Campy and Shimano parts. Just run it so
the cable only goes on one of the pulleys, and the cable pull will
stay normal.
