Bsun Roche Limit

BSUN

Standard ProfileLinear5

Switch Overview

The Roche Limit was designed by Blackberry Studio and made with BSUN newest mold set, with smoothness, typing feel, sound and consistency all rated very good. BSUN uses a new factory lube method that avoids overlubing: a 205 and 105 mix on the sliders plus dry film lube on the stem sliders and spring. Sound leans toward a medium but full clack。
