I've put many a mile on a 24-tooth sprocket (~7,000 Rpm) on my PR with no bearing problems.I've heard some people say that it's easier on a drive train if there's not a perfect division between front and rear sprockets (i.e. 21 t front x 42 t rear = bad, 23 t front x 42 t rear = good) but I don't know if this is a real thing and if it is, whether it really means anything in practice.
