Introduce a seamless and efficient solution to adjustable headset bearings with Problem Solvers' innovative Adjustable Headset Spacer. Designed to install under the stem, this specialised tool provides an easy, reliable alternative to using a star nut.

Forget about the hassle, as this adjustable spacer provides simple, effective bearing preload adjustment. It snugly installs between the stem and headset, eliminating the need for a star nut or preload compression plug. This makes it an ideal addition especially for carbon steerers.

It’s not just its functionality that stands out. The spacer is crafted from hard-wearing and stylish black anodised aluminium guaranteeing durability and sleek aesthetics. With its 12mm height, it requires a minimum stack height of 10mm below the stem, ensuring a perfect fit for a seamless transition.

With its micro thread design, the Adjustable Headset Spacer enables you to apply the perfect amount of pressure between the base of the stem and the top of the headset for optimum performance. Simple and effective, it's the precise detailing your bike setup needs.

Don't settle for less when adjusting your headset. Choose Problem Solvers' Adjustable Headset Spacer for a straightforward, efficient solution.
