Seat post size is the inner diameter of top of the seat tube (usually single butted - thin part at the top) - change the tube = change the seat post. When the Sam got 0.2 thicker tubes (same outer diameter = same lugs), the seat post got smaller -> 27.2 minus 2 x 0.2 = 26.8.

I believe it's a matter of what seatlug is used for a particular model. 27.2 was on the MUSA frames, 29.8 was the socket-style lug originally used on all Clems and now only the big ones, 26.8 is the lug currently used on the smaller Clems and all MIT fully-lugged bikes. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
