Drop your saddle out of the way for steep, technical descents and pop it back to full pedalling height in an instant. The PRO Tharsis dropper gives you a generous 200mm of stepless travel, so you can dial in exactly the seat height each section of trail demands without ever stopping.

Highlights

• 200mm of travel for big descents and confident, low-saddle cornering
• Infinite (stepless) adjustment so you can set any height on the fly
• Internal cable routing for a clean, protected and quiet cockpit
• Mechanical cable-actuated action that is reliable and easy to service
• Lightweight full alloy cartridge and alloy body with titanium hardware
• Two-bolt, 3D-forged alloy head for secure saddle clamping and easy angle adjustment
• Zero-offset (in-line) head and 30.9mm diameter

Built to take a beating

The Tharsis pairs a full alloy cartridge with an alloy body to keep weight down while standing up to hard enduro and all-mountain riding. An oval stanchion profile helps resist twist, keeping the post smooth and predictable lap after lap.

Easy to live with

The internal-cartridge design is built to be serviced rather than thrown away, with replacement cartridges available through authorised dealers so you can keep the post running season after season.

Set up and dialled in

The traditional two-bolt, 3D-forged alloy head with titanium hardware makes saddle fitting and fore-aft angle adjustment straightforward, while internal cable routing keeps the cable tucked away inside the frame for a tidy look and fewer snags.

Compatibility & fit

This post has a 30.9mm diameter, 200mm of travel and internal cable routing, so check that your frame accepts a 30.9mm post, routes the dropper cable internally and has enough seat-tube depth for the full insertion length (total post length is 500mm). It uses a zero-offset (in-line) head suited to standard round saddle rails. Note that the post is supplied without a remote lever, so you will need a compatible dropper remote to operate it.
