Raise and Lower the Heaight of You Saddle Quickly
The dropper post 30.9mm is a practical upgrade for riders who want fast saddle height adjustment without remote levers, external cables or extra handlebar clutter. It uses a manual switch positioned under the saddle, so you can raise or lower the seat when your riding conditions change. This makes it useful for trail riding, shared bikes, commuter bikes and general mountain bike use where seat height needs to change quickly.
To fit a 31.6 mm seatpost tube we have 31.6mm seatpost shims available.
With 125mm of travel and a 400mm extended length, this manual hydraulic dropper post gives you a useful adjustment range while keeping the design simple. The 30.9mm diameter suits bike frames with a matching 30.9mm seat tube. Therefore, it is important to check your existing seatpost size before ordering.
