Hi tri,
The post isn't reversible, but the shaft is the same shape as the old S5 (and new S3 and new S2), so now all current S-series can swap posts - including the 2-position post. All posts are available after market, but if you know someone with one they might swap you for your single-position post.
Cheers,
