Hi there!
I currently have a canyon grizl 7 aluminum with a grx 2×12 setup. Front chainring set is a grx 610 and the rear derailer is a grx rx820. I want to go 1 by as I’ve heard is less hassle and better for the kind of riding I’d be doing (mainly flat, some hills, mainly going for speed). I really like the idea of a 11-46 or even an 11-51 cassette but I’m new at this so I don’t know what would need to be replaced and really what I’m in for. Any help with this would be super appreciated!
Pic for attention haha.

Why would you need a 11-51 cassette for mostly flat, some hills? Also 2X is more about speed…
You’d need a front chain ring, offset to keep a good chain-line (easy if chainrings are direct mount, not bolted) a cassette you want and a derailleur that supports the cassette’s range.
2by gives superior range – you basically have 1 ring for flat/downhill and a small one for steep climbs. Super useful if you’d ever have your bike loaded for bike-packing.
Literally the sole reason for a 2by is flat and fast riding.
I dont know who gave you this advice, but the opposite is true.
A 1by is great for bikepacking, climbing or situations where quick and huge gearchanges have to be made. Mountainbike have switched over to a 1by because it enables them to go from a high gearing al the way up to a very low gearing very quickly to get over some steep incline with poor gri just to get up again to get back to speed quickly.
For ultra events or bikepacking it is great because yes, a 1by is easier to shift and maintain and it’s another component less to break down potentially.
On flat terrain with hills you don’t need to shift gears so extremely and you need a gearing that is closer together so you have a wider variety of cadence/torque option in smaller steps.
Downgrade but go ahead and try. Only couple hundred bucks for the experiment
How does the 2x hassle you today..?
That’s the opposite advice…
I have a 1x, 38/ 11-46. Sometimes I wish I had a 2x but on my daily ride, I have a 2 mile 1500 ft climb and I love the 38/46 combination
