Gentle and secure expander plug for 1" carbon steerer tubes

Protect your lightweight composite fork while achieving ideal headset preload with this 1" expander plug from FORCE. Conventional star nuts can score, crush, or crack delicate carbon fiber layers inside the steerer tube. This expander plug is specifically engineered for 1" carbon forks, expanding evenly to spread clamping forces over a wider interior surface area.

Featuring a 40 mm contact length, the plug offers substantial internal reinforcement against external clamping pressure exerted by the stem bolts. This dual support ensures a rock-solid anchor for your stem while keeping steering tight and wobble-free. Crafted with classic FORCE durability, it is a long-lasting component for fine-tuning your front end.
