This article covers DUCKY ゲーミングキーボード One 2 SF RGB 65% 赤軸(英語配列) dk-one2-rgb-sf-red ［USB.

Overview

The DUCKY One 2 SF RGB is a compact 65% mechanical gaming keyboard, model dk-one2-rgb-sf-red, equipped with Cherry MX Red linear switches and an English (US) keycap layout. It strikes a balance between desk space savings and usability by retaining arrow keys and a few function keys. The keyboard features full RGB backlighting, a 1000 Hz polling rate for fast input response, and a wired USB connection for stable performance. Its build quality and switch reliability make it a popular choice among gamers who prefer a smaller form factor.

Connectivity & Compatibility

This keyboard connects via a fixed USB Type-A cable (non-removable). It is compatible with Windows, macOS (with limited function), and Linux via plug-and-play. It supports full N-key rollover over USB, allowing simultaneous key presses without ghosting. Due to the compact 65% layout, users accustomed to tenkeyless or full-size keyboards may need a short adjustment period. No additional software is required for basic operation, but Ducky provides a companion app for macro and lighting customization (available on Windows).

The package includes only the keyboard; no keycap puller or extra keycaps are included. The keyboard sits in the entry-to-mid range gaming keyboard segment, standing out for its Cherry MX switch reliability and Ducky's robust construction. It appeals especially to enthusiasts of the 65% form factor who want a premium typing and gaming experience.

Best Use Cases

The DUCKY One 2 SF is ideal for gamers who need to maximise desk space. Its 65% layout leaves ample room for mouse movement in fast-paced genres like FPS and MOBA.
