104 or 110 bcd for 36T chainring?
I wanted to assemble a 1x crankset with a 36T chainring (for hybrid). Is it easier to choose 104 or 110 bcd for this? Is it easy to put a bashguard on both sides?

the frame and wheel will determine the "ease" of the install... 104mm BCD is a 4 spider arm MTB crank size... 110mm BCD is an Old mtb, or Road size, plus it's a new style, assymetric hollowtech II spiders, crank size.
things to consider on the frame.. the distance between the inner faces of the rear dropouts.... and this will dictate the optimal CHAINLINE desired.. the number of rear gears can also be a factor...The Width of the Bottom Bracket will also help determine the Crankset that will fit up easiest... 68mm is the standard Road spec... 73mm is the standard MTB spec.
you must also consider crank arm clearance in relation to the frame's chainstay (lowest rear tubes on the frame) tubes(AKA: Q- factor)... Road cranks usually hit those frame tubes on MTB bike frames.
Measure between the rear dropouts of your frame, and post what bike make and model it is.. model year info is a big help.. "hybrid" is a very flexible term.... Wheel size helps too, as in 700c or 26" tires?
as to the bashguards.. the 104BCD will be best for that.

I was thinking about the Bombtrack Munroe AL frameset. It would be running maybe 27.5x2.00 tires. Does it make a difference if I try 11-36T cassette instead of 11-34T?

the cassette won't matter in relation to the crankset.
the stock crankset is a square taper MTB 104BCD on a 119mm BB and the BB is 68mm wide.
why are you not just buying the stock bike? how much are you going to spend on that frame, anyway?

I don't know your set up but on my old bikes I had no problems going to a 34T ring on my 110 doubles.
I also had to go to a long cage derailleur to accommodate a 34T cog on my freewheels. That gave me a 1:1 knowing that if I needed anything lower I could just go to my Size 12Ds.

From my experience, there are more selections for crank arms, chainrings, and bashguards in the 104bcd.
104 will also allow you to go down to 32t or 30t in the future if needed.

If you choose two chainguards, do you add a spacer on one side? I mean the side of the bottom bracket. My other choice might be one chainguard but would I be better off with one of those anti drop chain adapters or whatever you call it?
