AA couple of weeks ago, I noticed my teeth were getting very pointy indeed. No wonder the grinding noises were getting louder and louder.
I tried all over the internet to find Campagnolo chainrings in stock, but it was not to be. It wasn't to be a couple of years before when I tried to buy Campagnolo chain rings then either. That time, I bought TA rings, but I've never been happy with them, they just didn't look right, and they feel flimsy to ride.
I was secretly pleased to see my TA rings had worn out. I bought some new style Stronglight rings and replacement chainring bolts (you nearly always strip standard Campagnolo bolts during disassembly in my experience, they seems to weld themselves together with the rings).
In less than an hour, everything old was new again, and quiet as well. Highly recommended,
Here's what it looks like:
