TranzX SP19 External Dropper Seatpost 100mm Travel 30.9mm Diameter
The TranzX SP19 External Dropper Seatpost offers reliable saddle height adjustment with a simple and easy-to-maintain external cable system.
The cable exits from the mid-cap of the seatpost which prevents cable movement when adjusting saddle height, helping deliver smoother operation and reducing cable wear over time.
Built from durable 6061-T6 aluminium, the SP19 provides dependable strength for mountain and trail riding. The 0mm offset head and secure saddle clamp ensure a stable saddle position while the hard anodised shaft improves durability.
A handlebar dropper lever is included so you can quickly raise or lower your saddle while riding.
