Ok so although the cracking probably isn't good that isn't what was making the clicking noise. That must have been the stem slipping in the steerer tube or something, as it came loose completely today and won't tighten enough now (I could ride on it but not hard, can't skid, etc.). Lucky this happened on an empty road where I could fall safely and with as much grace as I could manage, and not halfway down Reigate Hill...
It sucked having to ride home gently without skidding, and it was so windy the stem actually came loose again just by the force involved in keeping my wheel straight against the gusts.
