Hi peeps and Campagnolo enthusiast!
Tried to insert a 27.2 size seatpost to 27.2 insertion but was too tight and I wouldn't want to damage it.
Could anyone know which is the specific Campagnolo tool to enlarge 27.2 insertion diameter? Any clearer picture or code name for this particular tool as attached.
Thanks and cheers! Aaron

find a Professional Bike Shop, with an adjustable reamer, a machinist's tool.
that is what the picture shows.. it is not a Campag tool.
with your seat post in hand, the shop can shave out
just the precise thickness, required, till the post fits..
I have done this , myself, to modify my Bridgestone RB1, frame
from 27.0, to fit the 27.2 post I wished to use.
I kept trying to get it to fit , a cut of maybe .01mm at a time, till it fit,
that way the cutting result was just right..

If it they're both really 27.2mm, you shouldn't have to ream it. Spread the opening a bit with a screwdriver and grease the inside of the seat tube.

+1 but it depends of the frame too. Some frames come out of the factory un-reamed and by heat tubes tend to warp and deform aswell. Pretty much all the good stuff should some reamed from factory.

a lot of Steel frame builders, the Italian names of fame, send out the frames,
expecting the retailer to do the final prep work, face and cut BB, reaming ,
fork crown seat cutting, etc.

I'll get me coat.
Brake cylinder hone. That will clean it out enough to get the greased post in nicely.

I bought a new.seat post for my old vintage steel bike and some sand paper did the trick on the post and not too much at that.

@fietsbob-Most of the shops here no longer have the right tools for vintage steel bikes due to carbon bikes which require less prep work.
Furthermore, shop assistants are young and less experience in steel bikes and never seen this particular tool.
Anyway guys, thanks for sharing your experience and advice. cheers!
