@Cake as @Scrabble said, my 24h SP 9series on a 35mm crabon rim is really flexy laterally, probably because the flanges are too close together for 24spokes. Only persue your plan if you're going for disc braks (I guess you are) and can cope with some wheel flex, I'm on rim brakes and my shitty choice of parts combo has been an expensive mistake.
