Burley Rock 'n Roll cable routing question
Hello everyone!
I have a question about cable routing on a donated Burley Rock 'n Roll tandem that I'm working on for my bike co-op. The shifter cables are internally routed and come out the back, open end of the down tube. As they exit the down tube, they directly contact the back of the rear bottom bracket shell. Should there be a cable guide to protect the bb shell from the cables? I don't even see any mounting points for a cable guide. It just seems odd to me.
Are there any Burley owners in this forum who can verify if what I'm seeing is correct or if the bike is missing a component? I'm unfamiliar with tandems, and even one of the co-op's senior mechanics, who is an avid tandem enthusiast, is baffled by this cabling situation.
Thanks!
