Replaced my crackset, chain keeps popping off the small chainring under load Looking for a little lower gearing on my gravel bike, I replaced the crankset with a FSA Omega with 46/30 chainrings, along with a new bottom bracket &amp; chain.

If I stand on the pedals while on the small chainring, I can get the chain to slip &amp; pop off the chainring. This makes starting and climbing pretty rough ;)

The front derailleur looks to be adjusted correctly. 

I'm looking for other ideas of what could be causing the chain to pop off, or maybe the FSA Omega crankset is just incompatible with my bike?
Assuming you have a 10sp RD 350 SS short cage (R350 GS seems to be a 9 speed item), you have possibly exceeded the total capacity and are not getting enough chain tension.

Capacity with 48/34 rings was 48 + 36 - 34 - 11 = 39. Capacity with 46/30 rings is increased to 46 + 36 - 30 - 11 = 41. AFAIK, only long cage derailleurs for triple rings have that much capacity.

Do you really need a 30t small ring? Would increasing it to 32t - to decrease the total capacity - be ok for you? Alternatively you could think about replacing the derailleur.
