2 x 10 to 1 x 10 conversion

My drivetrain is in a mess due to a leaky shed and was worn down anyway after a few years riding. I'm going to replace it with the following;

32T ChainRing
11-46 Sunrace cassette
Goatlink / long b screw for my deore mech

I also need a new chain, but can see people have ended up adding links to new chains with this combination. I'll probably get a KMC chain, but can anyone help me with the best size for this?

Thanks

Tbh I'd contemplate buying the shifter and going 1x11, should get a greater choice and should be a bit morw availability in future.

Chainwise any should do. They'll all be long enough.

Will need a new mech aswell, no?

But tbf a 11-46 10 speed has the same range as 11speed just less jumps.

Just go for the biggest, you'll need to size it for your specific bike anyway.

Most Mechs should run 1x11 from 1x10 fine.

I'd just caveat that with; Most aftermarket chains come over long, I think KMC come in 2 lengths (longer ones to accommodate 1x12 speed cassettes?) but either way you'll probably need to remove a couple of links. Might be an idea to count how many links are on your current chain for reference so you don't remove too many from a new chain.
