Based on the description, it should work. You’ll have to cut the chain.

> GRX 1×12 (10-51/40t)….is there anything to stop me swapping out the 40t for this third party 34t?
No, that will work as intended.
Two unsolicited comments, though:
* Being as those chainrings are made to order and that they are available in other configuration upon request that means they are (assuredly) CNC machined, and not forged. There is a very real difference in durability between the two, with forged offering superior lifespan.
* Also a 34T chainring is extremely low gearing for a “gravel” bike. That frame is often used as a touring bike, and even for that use, 34:10 is an extremely low top end ratio. I’m not saying it’s inappropriate for you, as you don’t mention anything about your use case or riding locations, but 34:51 is enough to allow one to climb 20% grades while loaded (if one can keep their balance). All I’m saying is make sure your powder is dry before pulling that trigger.
