RBW sells the Shimano CX70, which was designed for cyclocross dbls. Has anyone tried it on a triple? On my single bikes I find any derailler with a not too long cage works pretty well. but the tandem seems to be much more demanding. No doubt some of that comes from coordination between shifting and relaxing pedal pressure, and some of it comes from the extra long cables, but I suspect a third factor but haven't identified it.
When we got the tandem we initially had very poor front end shifting. I replaced the recycled rings with new TA's, reduced the range in both front and back, went from an XTR to an Ultegra RD. Everything worked great for 4 or 5 years, then this year I broke the Campy SR FD and replaced it with an IRD. Now I am struggling to get it working consistently. I am not alone in this. We do a couple of tandem rallies each year and I have noticed that a preponderance of mechanical problems involve front end shifting.
