F1 Seamless shift gearbox model
A precision-machined 1:2.5 scale model of a Formula 1 seamless-shift gearbox, the mechanism that changes gear in 10 milliseconds and defies mechanical logic to do it. Build it yourself. Understand it forever.
Every component. Machined to pinpoint accuracy.
This isn't a static replica. It's a faithful, working recreation of an F1 gearbox internals at 1:2.5 scale, machined from high-quality materials
Make it yourself.
Assembling this model, component by component, you don't just own an F1 gearbox. You understand one. When it's done, rotate the barrel, watch the forks walk the dog rings between gears, and see forty years of Formula 1 engineering resolve in front of you.
No workshop required. Every part arrives finished and ready to assemble with step-by-step guide.

Model Features
Twin selector barrels. The breakthrough that made seamless shifting possible. One barrel for the odd gears, one for the even, operating independently just like the real thing.
Dog rings with asymmetric dogs. Steep on one face to pull into engagement, sloped on the other to push out under back-drive. The tiny detail that makes the "impossible" 3-millisecond overlap survivable.
Input and output shafts with full gear clusters. Every ratio a meshed pair, spinning together exactly as they do at 15,000 rpm.
Selector forks, shift actuators, and a brass oil pump. Right down to the aluminium casing halves and rear cover, complete with bearings.
Black display plinth with engraved plate. Because when you've built it, you'll want everyone to see it.
