Bent seat tube

(1/7) > >>

ammacopij72:
Just noticed I might have a bit of a disaster here, can't get the seatpost into the tube as there is a slight bend/kink in it. Any ideas on how to resolve this without destroying the (new) powder coat lads??  "help" "help"

 difficult to put right.  Easiest option is to find a slightly narrower post( they do vary in diameter from make to make)  and live with it. Without cutting it out and fitting a new mast all I can think of is a well greased post knocked down which may straighten it a bit.... Or get stuck :/

Cheers fella, can't believe I didn't see it before getting it powdered.. The problem is compounded by the fact that I've had the layback powdered too..

Might try running some sandpaper down the tube to see if it makes it any better and then try the grease and rubber mallet technique, fingers crossed!!

I would try that first mate, fine sand paper or wire wool then like you say grease and a rubber mallet. Should sort it :daumenhoch:

Taipan:
I had an old seatpost taken off a GT pro stickered up as a GT post,I stripped it of its powdercoat it didnt have a GT stamp? but the post is deffo thinner (still strong) than the ones available today,so bitd they must have been a lot thinner,so look around for an older post maybe?
