18" Scandal, Hope BB, how many spacers to use on the drive side?
I use 3 on mine to try and push the cranks away from the chainstay.
I have FSA afterburners.
Try and get as much clearence as you can as you WILL get chainsuck.
chainsuck in caused by transmission components, how colse the chainrings are to the frame determines what happens to the frame if it occurs.

Sorry dont believe it. Most inbred/Scandal riders experience far worse chainsuck due to the chainstay being so close to the chainset. I run steel rings and change them regularly and still get awful chainsuck. The fact Brant has changed his chainstay design must be evidence that there is a problem.
I agree a worn transmission will generate chainsuck but it is made far worse if the chainstay is so close to the chainset.
Think he's worried about frame damage if the chainstays are close and chainsuck occurs
No On-one experience but this is my logic
A worn/sticky ring will lift the chain
If the chain doesn't touch anything it will normally drop away, unless its really bad and meets the chain at the top
But if the chain touches the chainstay then it is pulled, into the gap. Hence chain suck.
On the Genesis website its stated as what limits how far apart they'll set their chain stays
On One present their chain says as being a sort of no brainer. Clearly its not, its a a design compromise, just like any other arrangment.

"There is a flipside to adding mud room for the tyres though, it’s all to do with chainsuck. Chainsuck is caused by worn or dirty chains sticking to the chainrings and being dragged up between the stays and the chain rings. This can cause a lot of damage to frames, especially to the thinner walls of steel chainstays. Keep adding tyre room and you loose chainring clearance and risk severe jamming of the chain. We designed our chainstays to offer as much mud roonm as possible with just enough chainring clearance to allow a chain to pass between the chainset and stay without causing excessive damage - in most cases it’ll pass through without a scrape."
