HMX
Hmx X Phynikeys Chu







HMX Chu, also known as HMX Raw, is Phynikeys' first design project. It uses a relatively basic but reliable material composition of nylon housing and a POM stem. With HMX's precise molding it delivers a solid, clacky sound profile, and the typing feel matches other HMX options. Recent production uses improved leaf springs, HMX's answer to the leaf ticking issue. Factory lubed with mixed GPL105 and GPL205 on the leaf spring, stem feet, and bottom housing rails.
