Hyperglide-c freehub with larger small cog?

Hi, I have a Trek 950. I've been thinking about replacing the rear cassette. I says Hyperglide-C on the lock ring, and AG on the cassette. It's an 11-28 cassette. Currently using an IG chain.

So my question is, would a 14-32 cassette work or how would I make one work?

A 14-32 will definitely work on a Hyperglide-C body. It's when you try to go the other way, using an 11-X cassette on a non-Hyperglide-C body that you'll run into trouble.

If you can find a 14-32, sure it will work. The body doesn't care if you use a last-position cog larger than 11T as long as you use the cassette's supplied lockring.

You'll need to check your chain length with the new larger cassette. Should probably just get a new chain to go with it though anyway.

Is this a 7 or 8 speed?
I'm not aware of an "AG" cassette, but a 7 speed 11-28 is an "AC". (AH for 8 speed)

Doing a bit of searching, assuming you do have a 7 speed, it appears you have either a 1994 or 95 bike w/ 22-32-42T rings.
IF so, do you really want a 34T large cog with a 22T granny ring?
