Jtek Shiftmate 1 help needed

[gxaustin]

In this case (Campag 10s levers, Campag 9 or 10 front and rear derailleur, Shimano 9s cassette) it does work perfectly. I've been using that combination for over 20 years

Thanks for finally explaining

[gxaustin]

And 9-speed cassettes are probably cheaper. So why spend extra?

Fair enough but a shiftmate costs about £30

got it working reasonably well now. Not convinced it is the real deal. Time will tell. I had too much slack in the cable somewhere.
