Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

The 727 takes a 27.2 post. Why wouldn't it fit?

Well if you're thinking about the aero portion sitting flush with the aero seattube, it's not going to happen.....

Nope... that's why there's the 27.2mm; that's the seatpost diameter... which varies among frames, although 27.2mm is the most common.
Your road bike takes a larger seatpost size.

ah diameter that's the word i was looking for . so different bikes have different diameters ? and i think you mean my track bike takes a larger seatpost size ? because the roadie was too small and it just fell all the way down .

Yes and yes. I thought you were talking about a newer road bike as these days road bikes usually take larger posts because bigger is better apparently; points toward deda releasing a 35mm clamp bar and stem.

Yup, larger diameter for seatposts for stiffness; handlebars for ergonomics and stiffness.

My pleasure.
