There's not much below what is shown so it's a wonder it didn't snap or cause problem to the seat cluster. Normally I would polish it up, but in this case I will likely need to secure a new post. (Of course, the exorbitant ebay seller pb*bikes has the market on replacement Birmalux seat posts covered. )
