Keygeek Full Nylon

Quick Summary

The Keygeek Full Nylon is a light, all-nylon linear designed by XL Lab to deliver a clacky, concentrated sound with real bass underneath. By building the stem, top and bottom from nylon (with a fiberglass-loaded bottom), it sounds distinctly different from the usual POM or LY linears — sharp on top, weighty below. At 37g it is fast and easy, and it is one of the more characterful budget linears around.

Specs and Feel

Actuation is 37g rising to a 42g bottom-out on a 22mm KOS single-stage spring, with 2.0mm pre-travel and 3.8mm total travel — a light switch with a slightly longer-than-average throw. The stem is modified nylon, the top housing is PA66, and the bottom is N5 nylon reinforced with 50% fiberglass. That full-nylon recipe is exactly why the sound profile reads high-pitched and clacky yet “concentrated,” with audible bass: the nylon dampens and deepens while the heavy fiberglass fill adds the sharp, clacky top end. Stock smoothness is good thanks to the factory lube, and the longer travel gives a satisfying, full keystroke.

Tuning

The Full Nylon is smooth stock and built around its sound, so go light if you tune at all. It comes factory lubed; a heavy re-lube would mute the clack and dull the bass that make it interesting. If the 22mm single-stage spring pings, a careful spring lube is the safe fix. Films are optional — the nylon housing already deadens nicely — and would tilt it slightly more muted while tightening wobble. For most builds, leave it stock and let the nylon do its thing.

Verdict

Buy the Keygeek Full Nylon if you want a light linear with a distinctive clacky-but-bassy signature that stands apart from typical POM switches. Skip it if you prefer a creamy, smooth-and-quiet profile — a POM-blend like the Keygeek Cera or the Azure Sky Blue suits that better. Against the bright, sharper Keygeek M3, the Full Nylon trades some top-end clack for fuller low end and a more rounded sound. It is a genuinely fun switch and an easy recommendation at the price.
