Race Face Aeffect R Dropper Seatpost

Yes, the Aeffect R is designed exclusively for internal cable routing. You will need a mountain bike frame with ports that allow the housing to run through the seat tube and frame.

The Aeffect R features infinite travel adjustment, meaning you can stop the saddle at any point within its 125mm range. It does not have a mechanical travel reduction feature, so the total travel is fixed at 125mm.

This post uses a standard rail clamp design, which is compatible with the vast majority of mountain bike saddles on the market. It works with standard 7mm round rails.

The cable-actuated system is designed for simplicity and ease of maintenance. Replacing the cable or housing is straightforward and can typically be done with standard shop tools without needing to bleed hydraulic lines.

This specific model has a 30.9mm diameter. Before purchasing, verify that your frame's seat tube diameter matches this measurement, as seatposts are not universal.

7075 aluminum is a high-strength alloy commonly used in aerospace and high-performance cycling components. It provides an excellent balance of durability and weight, ensuring the post can withstand the rigors of trail riding without adding unnecessary bulk.
