Is anyone using this combo? I was just wondering what people do about the cabel channeling on the rear derailleur. I was worried it would fray at that point. Anyone have any tips as to what worked for them? I tried placing a piece of the liner supplied with the prime system there but it was way to big to fit in the channel. Thanks in advanced.

afaik the force rd cable path is similar to the red rd, i just run the cord through the guide, it's fine...

Yup! That's what it looks like. I was afraid it would fray. Thank you so much for taking the time to reply!

Mine did eventually fray (but it took a year) and so when I replaced it, I lined the cable that goes through there with a tight-fitting piece of mini-ilink liner.and reset the channel slightly (then polished it super smooth). Seemed ok. A gunged up cable elsewhere caused a rebuild (in haste) and I haven't rebuilt with another Cordz yet, but will re-do that system.
Red and Force are indeed the same.
