Nitto S84 Seatpost
The S84 is a very attractive seatpost notable for the lugged construction (the seatclamp forging has a lugged socket into which the chromo tube forming the pillar itself is bonded. The socket benefits from such lug ornamentation and drillings typical for the frame builders' art.
The seat clamp itself is a Nitto's twin bolt design as per the S72 for extra security and precision of adjustment.
