Hello,

So I currently ride a bike with a 30-42-52 by 11-28. I don't tour on this setup but I do ride long distances.

I have a 26-36-48 by 11-34 drivetrain on the shelf (with the appropriate derailleur and a separate chain), that I have never installed but bought for doing loaded touring.

If I were to switch back and forth between the two, installing the touring setup for my weekenders and switching back to the other setup for road rides and commuting, what do I need to be concerned about? Do I need to change the derailleur each time or could I just leave the long cage derailleur on all the time? If I need to change derailleurs, do I need to change the cable each time?

Thanks.
