    The PRO Tharsis 100mm Dropper Seatpost is a lightweight, infinite long-travel dropper seatpost. Available in a 100mm travel option, with internal cable routing, it features a full alloy cartridge and an alloy body to ensure it is lightweight and robust. The 27.2mm version boasts a 3D forged construction with an AL6061 alloy lower and an AL7050 alloy shaft, with titanium bolts which ensures that it tips the scales at just 405g.

Weight reductions are further enhanced by the use of an oval stanchion shape and a two-bolt style, 3D forged alloy head with titanium hardware.
