Bigger cassette...

So I got a longer-cage shimano 105 rear derailleur to fit an 11/32. Do I just use a mountain cassette? There's not a "road" one that I'm supposed to use with that derailleur right? Everything's interchangeable?

And any old 10 speed chain will do?

Bikes: Too many. Cannondale SuperSix, Trek Remedy 8, Trek Crossrip+ get the most ride time.

There is no difference between a "road" and a "mountain" 11-32. You should know that a rd5700gs has an official max cog size of 28, an a 5701gs has a official max cog size of 30. It will probably work but you may need to screw the b screw in a lot, or even backwards.

Use whatever 10sp non-campy chain you want.

The spacing is the same for any cassette that has the same number of cogs. "Mountain" cassettes have larger cogs on the low end for climbing. There are some "junior" cassettes that have larger cogs all through the range, i.e. instead of 11 tooth smallest cog, they have 13 or 14 teeth. Don't forget that you will need a slightly longer chain for the new larger cassette.

Cool, but I have the package right in front of me:

rd5701ss is 30T Max
rd5701gs is 30T for triple and 32T for double drivetrains

My bad, you're right.
