Durock Mamba 50g

Quick Summary

The Durock Mamba 50g is a JWK-made long-pole linear built for a loud, snappy typing signature rather than a deep thock. A nylon/UHMWPE top, POM bottom and LY stem combine into a switch that’s smooth out of the box and noticeably clacky on bottom-out. It’s an easy pick for anyone who wants a light, sharp linear with plenty of acoustic character and minimal fuss.

Specs and Feel

This is a linear in the truest sense: no bump, no click, just a clean slide from top to bottom. Actuation sits around 50g with a roughly 60g bottom-out on an extended long spring, so the keypress stays light and only firms up at the floor. The shortened 3.5mm total travel paired with the long-pole LY stem is the whole point here: presses land fast and end with a crisp, slightly higher-pitched bottom-out. Stock smoothness is strong, with only a trace of spring resonance and no real scratch to speak of. Stem wobble is well controlled in both directions, which keeps caps feeling planted on faster typing.

Tuning

The Mamba is perfectly usable as-is, but a thin hand-lube on the rails and a dab on the spring cleans up the faint ping and sharpens an already-smooth glide. Films are largely unnecessary given the tight stock tolerances. Skip them unless you’re chasing the last bit of consistency.

Verdict

Buy the Mamba 50g if you want a light, clacky long-pole linear with a distinctive sharp bottom-out and don’t mind a louder profile. It’s a poor match for anyone hunting a soft, deep, muted sound; the short pole pushes the opposite direction. For the price, it’s a confident, well-behaved linear that rewards a quick lube and delivers character straight from the bag.
