Can anyone tell me the outside-to-outside chainstay width on a Gus/Susie for crank clearance purposes?

I emailed Riv but haven't heard back, and I could use an answer sooner rather than later, since there's an item on eBay that I might need to snag ...

I'm specifically wondering if the White Industries A30 crankset (R30 arms with M30 73mm spindle) will work. That ends up with inner arm to arm measurement of 137mm. I have the arms and would like to just buy a 73mm spindle. The narrower Q would probably be a small bonus. But that seems kinda narrow for a bike the fits 2.8" tires.

Thanks!

Hi Paul - wanted to give you a measurement but need to know where specifically along the chainstay are you looking for the width, i.e., how far back from the bottom bracket shell? Also, are you looking for the inner width or the outer width?

Awesome. Thanks Ed!

Outer width of the chainstays. Crank arms are 172.5.

Small GBW with 170mm Silver cranks which measure out to ~185mm center-to-end on the crank arm. I took a measurement of the chain stay width at the longest point of the crank arm that came out to ~120mm.

Thanks Ed. That's enough info for me to take a chance on this setup.

I can't think of any reason the chainstays on the medium would be any wider, but even if they are wider, I doubt they're 17mm wider.
