Chainring teeth, should they look like this?
I have a 2013 Cannondale Synapse with a Sora triple chainring.
It's about 8 weeks and 500 miles old.
I've kept it clean and lubricated in this time, and today I had the chain off so I could degrease everything properly.
While feeding the chain back on, I noticed some of the teeth on the big ring are of different sizes/flattened at the top. Most are pointed
There's probably about 4 or 5 like this, with seemingly no pattern i.e. every 10th tooth
Any ideas/suggestions

I suppose, the chainrings are steel. Breaking the tip of a tooth would probably brake a bit more than just the tooth...
Thanks to both of you for the speedy replies
