Hi

Can anyone confirm what is the seat post size I need? I measure about 28mm but is that right?

Regards

Matt
 
Re:

Hmm, every proflex ive see, has been 27.2.

This is 6,5, 7 series and the very latest frames.

Your frame not included so could well be 28.
 
Re:

Bikepedia says 27.2. Just measured mine with calipers and yep, as said above they're 27.2.
 
Re:

I agree : 28mm for mine :?
Same size for 752, 852…
 
Re:

If you are using vernier cailiper then itll give the required accuracy, but not if using ruler.

If a ruler is all you have, wrap strip of paper and mark overlap, unwrap and measure distance between marms. Divide by pi.

A difference of 0.8mm will be 2.5 mm that is well within accuracy limit of a ruler.
 
Re:

Yep, just bought a cheapy kalloy type seatpost and 28.0mm fits perfectly.

Thanks all for your input.
