Triple setup
If you use a triple setup with chainrings, what size chainrings do you use ? And what cassette and derailleurs do you use ?
I have a campy setup and tried 30/42/52 in front -> 52 is too small. Plan to try 36/48/60 as soon as I get a 36. In rear I have a 11-23, I was disappointed to see that the pocket rocket pro frame with a campy derailleur cannot take a 26 or a 29t cassette.

Re: Triple setup
The chainring setup that came with our Twin Air tandem was 40/52/62. It uses a conventional double crankarm but they added spacers to attach the 40 tooth chainring. If you plan to use a triple setup, you need a long cage Campy rear derailleur. If you stick with double chainrings, you can use a short cage up to 26t cassette. If you go to a 29t cassette, you'll need a medium cage Campy derailleur. You could also use a long cage but I avoid using a longer cage derailleur than what is needed because the shifting isn't as quick. Don't forget to add extra links to the chain.
If you're looking to get a fairly low gear, I would consider a 29t cassette and purchase a medium cage derailleur. This will be simpler to install than a triple setup. You may also want to consider swapping the 13t cog for a 12t so you still have a decent high gear.

Re: Triple setup
I also have a triple set up and find it seriously under geared. Fine for pottering but hard when trying to keeop up with friends on full size bikes.
Have you changed yet and if so how was it. I am not sure what size outer ring I can fit but presently also have a 52 tooth job.
