Race Face Turbine R Dropper Seatpost

The 30.9mm diameter is a standard size for many modern mountain bike frames, but it is not universal. You should check your current seatpost or your bike frame's specifications to confirm the required diameter, as some frames require 31.6mm or 34.9mm posts.

Unlike mechanical droppers that lock into fixed positions, infinite adjustment allows you to stop the saddle anywhere within its 200mm travel range. This lets you fine-tune your seat height for specific trail sections, whether you need it fully dropped for a steep descent or slightly lowered for technical climbing.

200mm provides a significant range of motion, which is excellent for aggressive riding and getting the saddle completely out of the way. However, you must ensure your frame has enough seat tube depth to accommodate the post's insertion length and that your legs are long enough to maintain proper pedaling extension when the post is fully extended.

The Turbine R uses a standard cable-actuated system, meaning it is compatible with most aftermarket dropper post levers. While it doesn't come with a lever included, you can pair it with your preferred remote, provided it is designed for cable-actuated posts.

Internal routing requires your frame to have ports for the cable housing to run through the frame. If your bike is designed for internal routing, the installation is straightforward, though it does require threading the housing through the frame and securing it to the post's actuator mechanism.
