Most headset spacer kits ship with a stack of identical 5mm rings and call it a day. Ritchey's Classic Headset Spacers take a more useful approach: three 5mm and two 10mm aluminum spacers in one set, giving you 35mm of total stack to work with in increments that actually match how stems get adjusted on a fit. The high-polish silver finish with the white Ritchey logo is designed to sit alongside Ritchey's Classic stems, bars, and seatposts, but it reads as clean chrome-look alloy on any traditional build.

These are threadless 1-1/8" spacers built for a 28.6mm steerer outer diameter , which covers the vast majority of modern road and mountain forks running a standard upper bearing. If you're working on a build with a tapered steerer that runs 1-1/8" at the top — which is most of them — these drop straight on. They're not for integrated 1-1/4" upper bearing systems or proprietary cockpits like Ritchey's own Switch System, which uses dedicated interlocking spacers for internal cable routing.

The polished silver finish is the reason most people reach for these specifically. If you're building a steel bike, a classic road restoration, or any setup where black anodized spacers look out of place against chrome lugs and silver components, this is the kit that pulls the cockpit together. The 5mm and 10mm mix also means you can fine-tune saddle-to-bar drop in smaller increments than a single 10mm spacer allows, which matters when you're dialing in a fit and don't want to commit to cutting the steerer until the position is locked in.
