Should you find yourself touring with a campag race chainset on an old 10speed bike I’ve found the low 3 cog cluster from an 11 speed 11-32 cassette work fine with a medium cage 10 speed derailleur and the other 7 cogs in a custom cassette. Gives the same ratio as a compact 34:29 so I will be taking it to Andalusia later this year.
