Seat Post Question

[BMX1973]

Is it o.k to use a chrome steel seat post in an alloy frame?

Thanks in advance.

I think you should be ok but other radsters with loads more knowledge than me will know for sure. I know if you put an alloy post in a steel frame there is a possibility over time the post will seize/fuse itself in. With a chrome finish I can’t see that happening. Please wait for some other replies as this is only my uneducated opinion.
 
Hope you get the definitive answer soon

I agree with the above    thing is most of the problems are when somebody buys a frame thats had the post stuck in it for 30 odd years! thats when the problems arise    fit it and lubricate it best you can and you'll be fine 

PS...dont leave it in there for 30 odd years tho lol

Could an alloy post seize/fuse to an alloy frame.  If this is o.k am I right in thinking........

.......it's best to fit - alloy post / alloy frame and...
chrome post to a chrome molly frame... don't mix and match.

Any post can become stuck in any frame given the right (or more accurately I suppose wrong) conditions.

If you grease the post prior to inserting you will reduce the likelihood.

Oh, and stop over thinking this shit....its all about the look man

Im more interested i why every 22.2mm  seat-post that i buy is actually 21.9 when i measure it with my micrometer ,hence too small even when fully tightened ?

Inside of my seat post tube in the frame is 22.2 it's really got me stumped..
