I'm planning a gravel trip to the Sierra Nevada in May and am starting to think about gearing and could do with some advice.

My current setup is GRX 812, so 1x, running 42t front and 11-42t at the back. I want to go smaller, ideally 38t front and 11-46t at the back. Is that possible or beyond what the RD can handle? If so, what are my (cheapest) options?

I've only run the 817 RD up to 42T but presume by using a Wolf Tooth Roadlink you could get up to 46T. I actually bought a 46T cassette to try this theory out.

Could you not stick a lower chainring on also?

I hadn’t considered the Roadlink option, will have a look.

That’s the plan. I want swap my 42t for a 38t as well as go from 11-42 for a 11-46
