Tested by Riders, Proven in Europe’s Toughest Bikeparks
Since early 2024, we’ve been riding and testing Freakynuts® 15mm fork adapters to the absolute limit riding them hard in iconic Downhill bike parks Bikepark Leogang, Bikepark Samerberg, Bikepark Geisskopf, and Bike Republic Sölden. By 2025, the whole community followed us, putting them to the test worldwide and proving what we already knew: they hold up where others fail with their forks equipped with the Freakynuts 15mm adapter.
Together we Ride, Together we build
Freakynuts is More than a Product
We’re riders ourselves. We know your struggles, your challenges and that unbeatable feeling when your bike is dialed in and everything just fits.
What doesn’t belong in that picture are poor-quality parts, missing components, or even worse incompatible gear that just doesn’t fit.
That’s where our focus lies. We innovate and keep developing where the big brands stop, including the crucial 15mm Downhill fork adapter that ensures compatibility.
And we do it together with you, the Mountain bike community.
We never stand still. We develop and innovate alongside you, because every piece of feedback makes our products better and strengthens the entire community.
Have a Safe Ride,
Cheers, your Freakynuts Team
