I have a Argon18 Mercury with a 27.2 Seattube. I put a Richey Alu Seatpost (27.2) in and it worked fine. My Corima Carbon Seatpost just fits but is a bit tight.
Now I bought a Campy Record 27.2 and there is no way it will fit without major abuse on the Seatpost.
Anybody has similar experiance or a trick?
thanks
