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.

I agree with the above  :daumenhoch:  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  :daumenhoch:

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

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  :LolLolLolLol:

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.. ???
