Tharsis Dropper Seatpost, 100mm, 27.2mm, Internal, In-Line

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. The 30.9 and 31.6mm versions also pack a 3D forged construction; but with AL7075 lowers and an AL7050 shaft. 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. The new 2-bolt saddle clamp saves 45g while the oval shaft, improved collar design and optimized lower tube saves a further 25g. The Tharsis Dropper Seatpost 100mm is available in 27.2, 30.9 and 31.6 diameters.
