se racing seatpost question....

[waza04]

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

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

strange as the retro rippers come with just that thicker post though

It's Aluminium to cro-mo you get the fusion 


or alu to alu as well ?

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
