Sram crankset compatibility

Hi everyone,

I'm new to this forum, but I have a problem and was hoping to find a solution on forums, so if anyone could help.

I have a bike with SRAM s350 172.5mm 40T chainset, SRAM GXP 68mm BB and 12x142mm through axle rear hub, which should make my chainline 49mm.
As I have knee issues I am looking for 165mm crank arms (with 38T chainring). On SRAM site I see that Force 1 and GX-1000 crankset should fit, but I have 2 (actually 3) questions:
1. Does Rival 1 also fit those specs? As it works with 135mm rear hub (as written on SRAM web), shouldn't it work with 142mm rear hub as well, as they are basically the same? I'd rather get Rival as it is quite less expensive than Force and I don't race.
2. Do You know is there ANYWHERE in Europe that I could get some of these as I have searched every website I could think of and no one seems to have 165mm crankarms available?
3. What other 165mm 38T are available that are comparable to Rival 1 in price and spec?

Thank You.
