650A - you might want to consider a nice Sturmey Archer gear hub and maybe a set of cottered steel cranks and a sprung Brooks saddle

650B - often goes well with a nice generator hub, handlebar bag, Honjo fenders
650B - (aka 27-5) - that was a hella gnarly drop bruh.

650C - don't forget your Speedo?

You forgot one.

No, "Road or MTB" asked, and the OP answered "Road."

Now now, let's not be difficult.

Frame, wheels, and tires.

Plus all the other bits of the right sort for the frame (brakes).

Try it first, then muck with the gearing. It won't be a big enough difference to make-or-break the deal.

SO I guess the question is: What size tires is the OP intending to use on this 650 bike?
650cx23?
650BX32?
650BX2 1/2?
650aX 1 3/8?

Yep, I love 'standards' in the bike world.

If road bike and the rider is small like my 4'10" bride, I'd suggest 165 mm length crankset and short reach shifters/brake levers.

To clarify, this is a 54cm road bike frame built for 650 size wheels. All her bikes are 700c but she really likes the frame. It is offered with the wheels as a purchase option. Plan was to move the Tiagra triple 9sp road group over and was hoping it was easily transferrable. I also possess LR brakes if needed.

Assuming all of the parts are compatible (front drl size, bb threading, seat post, headset, etc) then you should be able to swap the group over with just a change to the appropriate wheels/ rubber and the appropriate reach brakes (as defined by the frame set, not the wheels).

As mentioned, you may want to make changes to the gearing, but that isn't strictly necessary for parts compatibility.

Enjoy the new frame!

650 what?????

[Ed-B]

What's the frame - who made it?

Unless this frame is a recent custom, it's most likely designed for the 650C wheel size - typically fitting skinny tires with 571mm bead seat diameters. And if so, it probably also uses short reach brakes.
