I know this has been discussed. I am referring to the rather vague shifting with the CoMotion Speedster et al and the 10 spd XTR rear derailleur. It's really not that bad, but I would like to tweak it a little to see if I can make it just a tiny bit more acceptable.
At the hand made bicycle show in Indy last week I talked to some of the tandem builders about this and came away with some suggestions.
1. Use the Jagwire tandem shift cable. Supposedly smoother and less likely to hang up.
2. Use the Nokon compressionless cable housing (looks like a series of beads). Pretty expensive.
One of the tandem had an arrangement where the nokon housing was used just on the section leading from the levers.
I plan to go through the shifting system and relube and tighten everything, but, how much of the problem is the XTR itself I wonder. Any thoughts?
