I use 32T front on my 1×10 bike, with an 11-36 cassette. Might be slightly too low, still getting used to it but I’d rather too low than too high. Also pedalling fast makes you look well pro.
I did have 34 on the previous build and I know it’s adequate- did a few known Orrible Climbs with it and it wasn’t too bad at all. But so far the 32 hasn’t been as much of a drawback as I’d expect it would.
Superstar XCR is a perfectly decent bit of kit, but I’d suggest if you can, spend a little more and get the MRP 1X- it doesn’t work any better but it’s quicker and easier to set up- has very simple chainline adjustment that can be done with the cranks in.
But, also I’d mention that a top-guide alone, unless combined with a clutch mech, isn’t quite up to the job. I used to tolerate it, on an older build, but it did drop the chain more often than you really want.
