Keygeek Y1X Linear

Quick Summary

The Keygeek Y1X is a medium-weight 48g linear built on Keygeek’s newest molds, tuned for a solid, planted bottom-out rather than a soft one. A fiberglass-reinforced PBT bottom housing and a KOS extended spring give it a firm, snappy feel with a clean mid-pitched voice. It’s a dependable daily linear for typists who want substance underfoot without a heavy spring.

Specs and Feel

This is a true linear — no bump, just a clean glide. It actuates at 48g over 2.0mm of pre-travel, bottoming out at 53g with a slightly shortened 3.6mm travel that keeps the stroke compact. The build is the story: a PA66 top housing over a PBT bottom housing infused with 30% fiberglass, which is what gives the bottom-out its solid, well-defined character — firmer and crisper than the soft, muted Keygeek deep linears. The Y1 stem keeps travel consistent, and the 20mm KOS extended single-stage spring delivers a snappy, well-supported return. Factory lube on this generation is applied more precisely, so smoothness is good stock with little scratch and well-controlled wobble from the new molds.

Tuning

The Y1X is designed to be good out of the box, and the upgraded factory lube backs that up — most builders won’t need to open it. If you want to deepen the firm bottom-out slightly, switch films tighten the housing and add a touch of body, but they’re optional. A light spring lube only matters if you’re hunting the last bit of ping in a quiet board.

Verdict

Pick the Y1X if you want a medium linear with a firm, solid bottom-out and a clean mid-pitched sound, ready to type with no work. It’s the firmer, snappier counterpoint to Keygeek’s deep-and-muted switches. If you’d rather a deeper, richer thock at the same weight, the Keygeek Y2 with its waffle stem tip is the better match; if you want lighter and poppier, look at the Keygeek Y3X. For a no-fuss solid daily linear, the Y1X delivers.
