Articles & Opinions > Campagnolo Ergopower with Shimano 9-Speed
Chris Juden, of Britain's CTC, points out:
"... we find there are several [reasons].
Loaded tourists, older riders, and anyone with steep hills (15% is common and 25% not rare on English country lanes) to tackle can use MTB [wide range] gears on a road bike. Also the Shimano 135mm hub is a stronger design axle, bearings, and spokes-wise.
But they want Campagnolo Ergopower because, well, it's more ergonomic, easier to use from the tops where tourists mostly have their hands, and doesn't have a wobbly brake lever or cables that interfere with a handlebar bag. Also the not-really-indexed front shift lets us do as we please with the chainset and front mech.
So thanks for the idea!"

I have to admit that any bikes, including singles, I build for my own use in the forseeable future will probably have this setup.
How did we do it? Because of the wide-range-gearing requirements of our tandems we use a Shimano 9-speed rear derailleur (XT-SGS) and a Shimano-compatible 9-speed cassette (11-32 or 11-34). Other large-capacity derailleurs may be available but nine speeds allow for a smaller "step" inside that wide range. Campagnolo 10-speed Ergopower Shift/Brake levers (the right or rear shifter MUST have the 10-speed "ratchet ring" – a 9-speed ring will not work,) and a Campagnolo "triple" front derailleur are also necessary. So far we have used RaceFace Tandem (54-44-32) and Shimano Ultegra Triple (52-42-30) cranksets, but any properly set up 9-speed crankset should work. The final elements are, of course, a 9-speed compatible chain and well-lubricated high quality cables.
I understand that a few have used, and prefer, a Shimano triple-compatible front derailleur. It does work but I found the standard compatiblity between the Ergolevers and a Campy front derailleur to allow for easier adjustment and a more forgiving trim.
The actual setup and adjustment of the system is identical to any other except:
The pinch-bolt on the rear derailleur, which holds the wire fast, should have a "hooked washer" between the head of the bolt and extension from the parallelogram. Normally, when using a Shimano shift-lever, the "hook" faces rearward and the "tab", which clamps the cable, points inward toward the rear wheel. The wire rests in the small groove in the body of the derailleur and points forward (see fig. A).
When using Campagnolo 10-speed Ergo-levers, however, the "hooked washer" must be turned 90 degrees so that the "hook" is facing the rear wheel and the "tab" is pointing directly forward. The wire is then wrapped tightly AROUND the "hook" and clamped beneath the "tab" so that the wire points outward away from the bike. The wire should then be running perpendicular across the small groove in the body of the derailleur (see fig. B).
Wrapping the wire around the "hook" may not be as easy as simply running it through the groove but it is necessary to making this combination work. I would also recommend adjusting the cable such that the extra "click" in the control occurs after the lowest gear rather than before the highest. This allows you to adjust the derailleur’s lower-limit screw so that the 10th gear position is "locked out" and the 10-speed control becomes, in effect, a 9-speed control.
