Our cassette has a maximum of 28 teeth, we ride on the road exclusively, and my largest stoker just barely tips 80 pounds. Needless to say, we're not a powerhouse team.
However, in looking at the page, I don't see any 10-speed cassettes listed with cogs larger than 28.
Here's the link to the 11-32 and 11-34 cassettes.

I guess they are on carriers. Right now we're using a 12-27 Ultegra cassette and so far no problems.
I would like the 11-32 but for that price, I think I'll wait until I hear more about it.
