Shimano 7-speed RSX cassette compatibility

Hi,
I have a 1990's peugeot roadie with Shimano RSX drivetrain. The chainwhel is 50/36 & the cassette is a 7 speed 11-24 unit. Problem is that these old legs cannot push that ratio up over the hill anymore.

Now I have seen a shimano 7 speed HG50 14-32 "F" cassette on sale in the US (expensive to ship to here in the UK), but it's advertised as mountain bike kit. Will that cassette be compatible with my setup?

Or any other kit suggestions (I can't train any harder!), thanks guys !

I suspect that going up to a 32T cog might be beyond the capacity of your mech. That said, I did use to run the 12-28T version on my RSX (which was also probably beyond the capacity) and didn't have too many problems. They're also a bit more available:

Many thanks for the help - I have bought a 28T and fitted it: the indexing seems fine on the shifter, pending a long ride to try it out next week.
