Is the Problem Solvers Headset Spacer Right for Your Build? The Problem Solvers Headset Stack Spacer is a clean, no-nonsense solution for riders dialing in their cockpit position on modern bikes. This 1-1/8 inch spacer fits the standard steerer tube diameter found on the vast majority of road, gravel, and mountain bikes, making it one of the most universally useful fit tools in the shop. Made from CNC-machined aluminum with a polished silver finish and no logos, it integrates cleanly into any headset stack without drawing attention. At 28.5mm inner diameter, this spacer drops into 1-1/8 inch steerers with ease and provides a solid, rattle-free platform when properly torqued. The silver polished finish complements silver stem hardware and headset components, and the logoless design keeps your cockpit looking intentional. Sold as a single spacer, so you can add exactly what your fit demands without accumulating a drawer full of unused pieces. Whether you're raising the bars for a more comfortable riding position or building a new frameset from scratch, this is the spacer to reach for.
