Title: Seat post sizes????
Post by: bmxboy70 on January 20, 2010, 09:21 PM

Ok guys and girls what sizes do seat posts come in? I have measured mine and it appears to be 23mm. The post I have is 22mm which I thought most are? Anyway are there posts that are 23mm or just below??? and has anyone got anything??

Thanks in advance Si. :daumenhoch:

Thanks for that! the post i have has a knurled bit on it and that holds ok but then the seat is way to high for racing?? I suppose I could cut it?

Simon,

Is it the Bully you're having trouble with?

Just a thought, but is it the seat clamp that's the problem rather than the post?

Yes it is the bully, but the clamps ok the post is only 22mm apart from the knurled bit which is 22.2mm so when I put it low for racing I don't like the way it clamps it bends the bolt! If I tighten on the knurled bit its fine but the seats to far up. After Karate I will do some pics! Anyway whats going on with the race is it on off or are we going somewhere else?? I'm up for anything just say the word! even a practice sess with the bmx boys!

Just use a shim around the post.  Cut a piece of coke can about 4 x 2cms,  works perfectly

Good thinking!!
