    I'm stonkered.

    Not long enough...I had to go with a 400mm on mine and 450mm would be better if I could find one.

    you can always try a 28.6mm seatpost that hopefully has a 25.4mm ID

    I just measured my kalloy uno, and it has 25.6mm ID, so you might want to try something cheaper.

    Thanks for the info. I just bought a Twenty and might be needing to replace the seatpost.

    I would suggest going with the longer aluminum alloy Kalloy single bolt model, it will lighten the bike a bit and allow for a modern single rail saddle to be mounted. FWIW I use a Brooks B67, but that is my preference.

    Diameter is 28.6mm a 400mm seat post will stow all the way down if that is a concern.

    I have a Brooks B67 that I am planning to use on the Twenty. The bike is currently stored with a friend so I'll have to see if a 350mm or 400mm seat post will work after I get the bike back.

    I could ride the stock seat post with a 32-33 inch inseam but replacing it lightened the bike a great deal and the stock post makes an excellent snipe as it is one sturdy bit of steel.

    I turned my seat post upside down, welded an extension onto the narrow end, inserted it into the steerer and added a modern MTB head thingo, and "HEY PRESTO" an instant very long head stem...... heavy as the Titanic, but STRONG, and I can ride with no hands....no brains, no teeth.

    28.6. Sheldon Brown used to have to attach a smaller seatpost on top of the stock one to get sufficient extension but now thanks to mountain bikes and oversized designs, aluminum seatposts are now available in the Raleigh Twenty diameter for reasonable cost.
