It is short, but perhaps not too short for mkatz. My calculator says this means 32 km/t at 80 pedal revolutions per minute, with those tyres. That's enough for a casual rider on flat ground and even slight downhill. Some older riders don't like that cadence. At 60 revs you get 24 km/t, still enough for casual riding on flat ground, but on any downhill you'll be coasting. Just putting the numbers out there. I have no idea how fast you like to ride, mkatz.
Also note that this gearing doesn't give you a very low gear either. If you're not very strong you may need to walk steeper hills, if you have them.
