EVO Seatpost Clamp

The 31.8mm measurement refers to the inner diameter of the clamp, which must match the outer diameter of your bike's seat tube. You can verify this by checking the specifications of your current frame or by measuring the outer diameter of your seat tube with a pair of calipers.

While this forged aluminum clamp is robust, it is primarily designed for metal frames. If you have a carbon fiber frame, you should consult your manufacturer's specifications, as carbon frames often require specific torque settings and clamp designs to prevent damage.

The chrome plating offers excellent resistance to the elements, but it is best practice to keep the area clean and free of grit. A quick wipe-down with a damp cloth after muddy rides will help maintain the finish and prevent any potential corrosion on the steel bolt.

Installation is straightforward and typically requires only a standard hex key (Allen wrench) to tighten the integrated steel bolt. Ensure you do not overtighten the bolt, as this can strip the threads or damage your seatpost.
