The ThinGears Difference

Fits Where Others Can't

Engineered for tight spaces. Clearances that would make other gears cry.

Lighter by Design

Every gram matters. Our gears weigh less because there's less gear. It's simple science.

Competition-Crushing Thinness

23% thinner than Brand X. We measured. Twice.

Technical Specifications

For the engineers who need numbers before they believe in thinness.

What Teams Are Saying

We had a 0.5mm clearance and no gear would fit. ThinGears fit.

That's it. That's the testimonial.

JJ Sessa — Team 4414

Saved 12 grams on our drivetrain.

I cried real tears. Every gram counts. My students think I'm overreacting but they don't understand what 12 grams means at this level.

Mike Corsetto — Team 1678

I don't fully understand gears but these ones are thinner.

Everyone on the team is very excited about it. I trust them. The vibes are good.

Dave Powers — Team 6328

I redesigned our entire gearbox around ThinGears.

My mentor asked why. I said 'because they're thinner.' He had no response.

Soren — Team 4414

While the competition stayed thick, we got thin.

Where It All Started

One gear. One student. One shop. The gear that launched a revolution in thinness.

When our team needed a gear thin enough to fit a clearance nobody thought was possible, we didn't complain. We didn't redesign. We made the gear thinner. And then we made it everyone's problem.
