how much clearance to the chainstay (to the side) do you have with your 36t oval chainring? I installed a Sram 36t oval on my spark rc and have only about 1,5mm. This seems kinda scary. Arent you worried about frame flex resulting in your chainring eating in the frame?
Thanks for your reply. Great! Could you maybe measure that clearance to the side of the chainstay? Looks like mine is much closer for some reason. Maybe due to the Quark spider? What frame size do you ride?
The offset of my sram chainring is 3mm, but Garbaruk also stated that their 36t oval direct mount also has 3mm offset. So that wouldnt make a difference, right?

Can you maybe mount chainring on the outside of the spider?
I have a direct mount chainring, so no spider… i could go for a 0mm offset chainring, but that may mess up the chainline too much maybe?
you have the sram one… garbaruk one is slightly outwards…
no, only from the inside !
That is not correct. For sram gxp (non boost) has a 6mm offset (inboard), bb30 has 0mm offset and a sram boost chainring on a dub crank has 3mm offset inboard.
Also, my chainring doesnt fit the other way around :-p
@Gabriel29: sorry for stealing your topic…

Ahh i get you now. If the gxp non boost is the reference, then boost is indeed 3mm outboard. 
From sram cranks perspective, gxp non boost is 6mm offset and dub boost is 3mm offset.
Anyway, all aligned again. I measured the distance between chainstay and chainring again, and the distance is a little over 1mm. If i add a 2mm spacer, would that be enough space? I think that would still allow me to tighten the crank and use the preload adjuster?
Late to this post, but also recently upgraded by 2019 Spark RC. I went with Elite Carbon Wheels (~1400g) with DT Swiss 240 Hubs. However, having issues with chain skip and shifting since converting over–working on mysterious issue now. Also, went with Carbon-Ti Axles which has improved the feel of the roll and has added a tiny bit of stiffness to the wheels. Looking also at the fall-line dropper to shave a few grams.
