  • 28.6 OD Columbus Life seat tube, what size seat post?

    Hand built frame, never built up, and I can see there is a bit of paint residue inside the seat tube from being powdercoated.

    I thought it was for 27.2 dia post, but it doesn't fit. Not sure if the seat tube just needs to be reamed for the 27.2 to fit, or whether it should be a 27.0 seat post ?
