How about a picture of the Xtracycle @Andy in Germany
The length of cable means you have less leeway to get the indexing right, especially as it has to go through all manner of bends to get to the rear mech, and there's that bit more to stretch. It's a slight niggle with a longtail such as this. I should use a tandem cable really, but I discovered after a previous outbreak of poor organisation that a regular cable fits -just.

Yes, you are ight. Assuming freehub is Hyperglide (one of the splines narrower) -am I ight in thinking that if I change a 7 speed cassette to an eight speed, I need a new hub for the cassette to sit on?
Campagnolo rear mechanism shift ratio (on the mech, not the cluster) stayed the same (at 1.5x pull IIRC) all the way from their early days up into the early 9-speeds, then changed (can't remember what to though)... that was around 2000, They might have changed again at 11. Weirdly if you fit a late 9 or a 10-speed Campy indexing shifter to an earlier derailleur it will work if you use a Shimano cluster appropriate to the shifter... Also if you ar etrying to mix and match speed ranges and component makers look at the JTEK Shiftmates and also the Hubub technique of changing the pull-ratio on Shimano mechs...Suntour's last stand was a 7-speed indexed down-tube system. It wasn't possible to upgrade this using Shimano or Campagnolo shifters because the pull ratios are different. But as long as you have same-same up front and on the derailer, then you are OK, it will work.
Everything remained compatible until Shimano's 10-speed Dyna-sys mountain groups came around. Then you again could not mix and match, which means you cannot use a road shifter with a MTB derailer and vice versa.
