Title: se racing seatpost question....
Post by: waza04 on April 05, 2011, 08:05 PM
hi peeps, i was looking through a few old adverts regarding the old rippers, and found one telling you about do's and dont's..... i noticed one had information regarding using the drop out savers and all that to protect them, and then noticed in small writing, it said do not use a fluted aluminium seat post,  :-\  does any1 know why this is? i know laybacks were a deffo no no, but thought a straight one would be ok. any help appreciated. cheers  :daumenhoch:

first off not sure if fluted posts came in 13/16ths but if they did i would imagine the reason would be that A) not enough surface area in the seat tube and B) ally to ally fusion  :daumenhoch:

If ally aint anodised it can react with the other part,causing seizing.
also if the two parts are a tight fit it can "pick up" on the other part,so as you try to pull/twist it apart it will get tighter and seize :(
i always use copper grease when installing ally parts,headsets,bbs etc :daumenhoch:
