the white bike has a 700/29er 2.1 inch Vittoria Mezcal on it, I used a Pacenti oversized BB from Frame Builder Supply and some CX double s bend chainstays with Paragon flatmount through axle drop outs. it is set up with 5mm worth of spacers to use an MTB crankset.
The red bike has 700 38mm Gravelking SK on it and crimped round chainstays, not sure which BB but it is over sized.

Thanks for the pic and details on your setup. Long chainstays, but if thats what itll take, i guess im in for a super stable ride!

Thank you for the pictures and details. On the White bike, do you know what CX double bend chainstays you used? Im guessing with me planning to use a tire thats 10mm smaller than what you have mounted, there will be enough clearance even with a 46/34 road crankset due to the position/curve of the stays along with a smaller tire so I can use more of the inner bend of the chainstay(i think that makes sense how i worded it?).
In the link above you can see the difference between mtb and cx stays the mtb stays have too much bend at the BB end.
Since you are looking to use a narrower Q factor road crank another option is to use the Columbus Hip stay sold by Nova. https://www.cycle-frames.com/bicycle...-for-29er.html
Good luck and post pics
