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......

Can you share the ad, please?

Reply that you are mostly interested in 650b tyres - could they confirm size on tyre? Easy Peasy

Hmm, could you get a centrepull pivot/stud to rim measurement from someone or somewhere, then ask the seller for a stud to drop-out measurement and go from there?

The French made for both wheel sizes with those brakes.
He says it's 700s - if it isn't, it's not as described so you can have your money back.
