I'm pretty much on my 200m gear for a keirin.
It would probably be too small to win a top level Keirin. It's perfectly fine for a cat 3. I've seen endurance riders with leg speed, e.g, Holloway or McCook pull off good Keirin results in a "small" keirin gear -- and I've come around said riders in smaller gears.
