The BDH S1 Sequential Shifter is a fully mechanical sequential gear shifter for sim racing, compatible with PC, that recreates the feel of a competition dog-box gearbox through its Dynamic Inertia Mechanism™.

Machined entirely from aerospace-grade billet aluminium with a hard black anodised finish, the S1 doesn't rely on spring tension alone: its proprietary weighted inertia system —with ball bearings, compression springs and internal dampers— produces a real momentum pulse on every shift, replicating the energy transfer of a racing sequential selector. Designed and built in York, England, it has a rally-focused long shaft and a high-impact feel for solid mounting on aluminium profile cockpits.

Key features of the BDH S1 Sequential Shifter

  • Dynamic Inertia Mechanism™: a weighted inertia system that translates lever motion into real momentum transfer, not just spring tension.
  • Dual-stage engagement: initial resistance, a crisp engagement point and a natural return, just like a real dog-box.
  • Full billet aluminium construction in aerospace grade with a hard black anodised finish.
  • Precision internal components: ball bearings, compression springs and dampers.
  • Rally-focused long shaft: an aggressive, high-impact feel on every upshift and downshift.
  • Versatile mounting: top, side or reverse mount via an integrated clamp for aluminium profile, orientation-switchable left or right.
  • Lifetime warranty against manufacturing defects.

Compatibility

  • Compatible with PC and all major sim racing titles that support sequential shifting.
  • Direct USB connection; works independently from the wheelbase.
  • It is a purely sequential shifter: there is no H-pattern mode.
  • Not compatible with consoles (neither PlayStation nor Xbox).
  • Mounts directly onto aluminium profile cockpits and rigs via its integrated clamp, with no third-party brackets.

Frequently asked questions

Is the BDH S1 sequential or H-pattern?

It is purely sequential (upshift/downshift); it is not an H-pattern shifter. For H-pattern shifting, BDH offers other models such as the H1.

What is the Dynamic Inertia Mechanism™?

A proprietary weighted inertia system that, using ball bearings, springs and dampers, produces a real momentum pulse on every shift, replicating the inertia of a racing sequential selector rather than simple spring tension.

What is it compatible with?

PC and all major sim racing titles that support sequential shifting input. It connects via USB and works independently from the wheelbase. It is not compatible with consoles.

What is it made of?

Entirely from aerospace-grade billet aluminium with a hard black anodised finish, with no plastics or generic parts, for heavy use and a consistent feel.

How is it mounted on the cockpit?

It supports top, side or reverse mounting via its integrated clamp for aluminium profiles, orientation-switchable left or right, with no additional brackets.

What warranty does it have?

A lifetime warranty against manufacturing defects, like the rest of BDH's mechanical shifters.
