The BDH H1SQ Dual Mode is a dual-mode shifter —H-pattern and sequential— fully mechanical for sim racing, compatible with PC via USB-C, with a 4 kg HE260 aluminium chassis and contactless Hall sensors, available in Silver and Full Black finishes.
Hand-crafted in York, England, the H1SQ integrates two independent mechanisms in a single unit: simply twist the selector collar to switch from an 8-position H-pattern shift to a sequential one, with no tools. With adjustable resistance, a Quaife WRC-style knob and high-tensile steel construction, it delivers a competition feel on aluminium profile cockpits and rigs.
Key features of the BDH H1SQ Dual Mode
- True dual mode: H-pattern (8 configurable positions) and sequential in a single unit, switching modes by twisting the selector collar.
- Adjustable shift resistance: tune the shift feel to your driving style.
- Premium construction: CNC HE260 aerospace aluminium and high-tensile steel, with no flex or premature wear.
- Selector collar with dual lock and a centralising CAM system for precise, error-free selection.
- Quaife WRC-style knob in nylon with a high-grip texture (M10×1.5 thread, compatible with other knobs).
- Contactless Hall sensors (zero lag) and proprietary BDH firmware, with no external power supply.
- 360° mounting with M8×1.25 points, compatible with most 8020 profile rigs.
