First setback on colnago build
 
Seller told me it was a 27.2 seatpost fellow c&v member sold me a great post and it's just a hair to big, guess I shouldve measured

Shawn... How close? Can you hone the ST, or will it need to be reamed??

I could force it
In but it would be super tight. Seems like maybe a 27 would fit but when I measured it was closer to 25.4

Most or all steel colnagos should be 27.2 afaik

That's what I'm thinking too. Maybe you just need to clean it out good in there?

Yeah , here's where I feel stupid, after I painted the frame I didn't want to clamp the frame on my repair stand. So I carved down a piece of a broom handle, so when I tightened it down on the wood it made it to small for my post. Good news
Is I figured it out and my new post fits.

25.4??:twitchy: that's way smaller than what most expect on a Colnago. That's even smaller than most French C&V steel bikes and close to like Vitus Aluminum bike territory.... What kind of frame tubing does it have??
I suspect a crushed/overtightened lug clamp......or maybe even a seat post tube shim sleeve, but that would be really easy to spot......

I'm shocked, I'm shocked I say. The painter is known for taking H tools to dropouts and charging for the alignment, dressing the BB threads and facing and "checking" the head tube facing and charging for it after the fact, and they missed an opportunity to make some dough "repairing" the seat tube and reaming at the seat lug... I'm shocked, they are missing their standards.

Yeah,I'm the painter

In my experience, 27.0 for a Colnago is not unheard of. But seatpost reaming is indeed usually the culprit.

It's fine now it's a 27.2 I pinched it to tight on a makeshift post that was a little to small.

understood, FUBAR!

i once buttoned the top button on my dress shirt to the SECOND button hole. like your seatpost, the shirt didn't fit right. and couldn't get the tie on straight either!

A colnago that I momentarily owned had a 26.8 seatpost.
