A 24 is teh smallest that will fit on a 74mm BCD.

The 22 mentioned was for a different crankset.

After you install it, put it on a workstand (or if you are like me, no workstand, instead you flip the bike upside down), put the chain on the 24 and then see how far you can get the chain to the smallest sprockets without getting to the point where the cage is too short to take up all the slack and the chain rubs against itself. (DJB was mentioning that earlier.) When I first switched to a 24T chainring I found that I could not use the 11 or 12T sprockets on the cassette, but those were highly cross chained so I wanted to avoid those anyway.

In my case I removed a 30T chainring to install the 24, if you had a 26, you might not have any problem using the chain on the small/small, although you should avoid it as being highly cross chained.
