Keychron KSA Profile Double-Shot PBT Keycap Set, 137 Keys White on Black Review (2026)

What the KSA profile changes

KSA is Keychron's own reworking of the classic SA profile, keeping the tall, sculpted, spherical top that SA is known for but trimming the height slightly and rounding the transitions between rows for a more ergonomic feel. The result sits between traditional SA and a flatter profile like Cherry, so typists who like the retro SA look but found full height SA fatiguing over long sessions may find KSA more comfortable. Because it is a proprietary profile rather than a clone of an existing shape, it will feel distinct from other keycap sets in a collection, and the row heights are specific to this shape rather than interchangeable with generic SA row numbering from other brands.

Build quality and legend durability

The set uses double shot PBT construction, meaning the white legends are molded as a separate physical layer fused into the black cap rather than printed or laser etched on top. That construction is the main reason double shot keycaps are valued over pad printed sets, since the legend cannot wear off, fade or rub away even after years of daily typing. PBT as a material is also more resistant to the shiny, greasy look that ABS keycaps develop from finger oils over time, so the caps should keep their matte black finish longer than a cheaper ABS set under the same use. At 1.6mm wall thickness with MX-style stems, the caps should feel solid and resist noticeable flex.

Layout coverage and what is excluded

This 137 key set is built to cover ANSI layouts across the common board sizes, including full size 100 percent, tenkeyless, 96 percent, 75 percent, 65 percent and 60 percent keyboards, which is a wide spread of coverage for one set. The listing notes that Menu, Scroll Lock and Pause Break keycaps are excluded from the set, so builders whose board relies on those specific keys in a visible position will need a donor cap from elsewhere or should confirm their layout does not need them. Because the fit is described around MX-style stems, it should work with most hot swap and soldered mechanical boards beyond just Keychron's own lineup, though it is designed with Keychron boards specifically in mind.

Where it fits best

Since this is a non-shine-through set, it is the wrong choice for anyone building around RGB backlighting who wants to see individual key legends glow, and it will look identical whether the board underneath is lit or not. It suits builders who want a clean, high contrast white-on-black look with a distinctive tall profile and do not care about backlighting effects, or who are running a single color underglow rather than per-key lighting. The white on black colorway is also a practical choice for shared or dim environments since the legends stay easy to read regardless of lighting conditions in the room, unlike some low contrast keycap colorways.

Value for the set

A 137 key set that spans six common board sizes in one package is good value if you regularly rebuild or switch between multiple keyboard sizes, since you are not buying a size-specific set each time. The proprietary KSA shape and Keychron branding put this above the cheapest generic PBT sets on price, but the double shot construction and broad layout support justify a mid-to-upper price bracket for keycaps. Builders who specifically want the SA-style tall profile without full SA height, and who are fine skipping backlit legends, get a durable, well-covered set that should outlast the keyboard it is installed on before it needs replacing.
