Race Face Aeffect R Dropper Seatpost

Infinite adjustment means you can stop the saddle at any point within its 170mm travel range. Unlike fixed-position posts, you aren't limited to set increments, allowing you to dial in the exact height you need for any section of the trail.

The Aeffect R features a 30.9mm diameter. You must check your bike frame's seat tube diameter to ensure a match, as this is a fixed size and cannot be adapted with shims.

This system is designed for simplicity. Because it uses a cable-actuated hydraulic cartridge, you won't need to bleed hydraulic lines like you would with a fully hydraulic remote system, making it much easier to service at home.

A zero-offset clamp positions the saddle directly over the seatpost, which can help steepen your effective seat tube angle. This is often preferred by riders who want a more forward, aggressive climbing position.

No, the RaceFace Aeffect R is typically sold as the post only. You will need to purchase a compatible cable-actuated remote lever separately to complete the installation.
