I seem to have a bit of an e-stay fetish at the moment. At the beginning of June I had none and now have 3 :oops:

Anyway the latest a Proflex 552 needs a new seat post. A previous owner has taken the novel approach of machining ( I use that term in the loosest sense of the word ) an oversized seat post down with an angle grinder it would appear. A quick search doesn't seem to yield any particularly accurate results as to what the seat post size should be. I measured it with my cheapo vernier at about 28mm but does anyone have one they could check or know for certain what the size should be.

Thanks in advance.
 
Thanks for the info. I recently purchased a Proflex 552 frame. I was looking for a SR Suntour SP12 NCX 27.2mm suspension seat post, and I was wondering if it would fit.
