Is a frame fit for 650b or 700c?

[uphilldowndale]

Hello,

Currently looking at a frame on eBay which I suspect might be for 650b wheels (french builder, direct mount centre-pull studs etc etc.). However, the seller says it is 700C. Is there any way to know for certain apart from putting a pair of wheels AND brakes in/on the frame??

Thanks

Surely the seller knows what wheels they used in the frame?

If they say it’s 700c……

I don't think they ever built it......
