Riding a ‘23 Cannondale Synapse 105 with the FSA Chainring. Chain keeps popping when I’m on the faster gears 10/11 gear on the larger chainring but not when I have it on a bike stand. It happens when I stand up to pedal. LBS did a tuneup and adjusted the rear and front derailleur and tension.

It does not occur on the smaller chainring, which looks relatively ok for me.

Am I good to swap out for a 105 50/34t 12 speed chainring, it looks relatively easy to do from what I saw.

The chain itself appears to be fine when I measure it, the LBS did remove one link.

    No. Those teeth are shaped for your pleasure.

    If you’re losing the chain on 50×10, the problem either lies with your FDer or chainline. Or the tension on your RDer.
