WORLD PREMIERE: Mount Your 15mm Wheels in the New FOX USD – Freakynuts Has the Fix
The new FOX USD (#Upsidedown Podium) fork has turned heads in the MTB world — with its fresh look, upside-down architecture, and downhill-inspired stiffness in a single crown package. But it also brought something unexpected back to the table: the well known 20mm front axle.
That’s might be great for stiffness and Self confidence.
But not so great if you ride a modern trail or enduro bike with a 15×110 mm Boost front wheel.
For thousands of riders around the world, this created an immediate problem:
Your expensive Boost wheels don’t fit.
Your hub might not have swappable endcaps.
Freakynuts Offers the Simple, Precise Solution
We at Freakynuts saw this coming.
So we built something that didn’t exist — but absolutely needed to:
A precision-engineered adapter kit that allows any modern Boost wheel (15×110 mm) to fit perfectly in the new FOX USD fork.
What’s in the Kit?
- Two CNC-machined fork adapters, made from aircraft-grade aluminum
- All components Made in Germany with high precision and real-world testing
- Worldwide sameday shipping with DHL
Our axle system differs from anything we’ve made before — it’s not a copy-paste solution and can also be ordered over our Webshop.
Whether your hub has swappable endcaps or not — this kit just works.
Who Is This For?
- Enduro riders upgrading to the FOX USD for its stiffness and USD tech
- Trail bikers who want modern ride feel without re-investing in new wheels
- Riders who don’t want to ditch their 15×110 wheelsets for a new standard
- Anyone frustrated by compatibility gaps between high-end components
If you’ve recently bought a FOX USD fork and discovered your Boost front wheel doesn’t fit — you’re not alone. And now, there’s a reliable fix.
