THE AC1

Handcrafted in Vancouver, BC, the AC1 blends stainless steel artistry with precision engineering, delivering an unparalleled riding experience.


Designing and building the AC1 in-house has allowed us to hone in on exactly what we feel a mountain bike should be. The first major design decision was building around a gearbox instead of a traditional derailleur system. The gearbox system allows us to build a more compact and simple package.

The gearbox works in unison with the i-Track patented high pivot suspension to deliver a supple yet responsive rear end. The MS3 stainless steel was chosen for the construction of the AC1 for its incredible durability and high strength-to-weight ratio, ensuring a lasting quality ride experience.

After years of meticulous development, we are thrilled to unveil the AC1 and eagerly await the opportunity to craft your dream bike.

Experience the exceptional ride of a custom-fit AC1, where speed feels effortless and comfort is paramount. Our rider-centric design prioritizes ease of maintenance, ensuring every component can be serviced with ease, whether in your garage or at the races. The streamlined gearbox drivetrain guarantees reliable performance in any condition.

THE RIDE

GEOMETRY & DESIGN

The AC1 features a 4-bar suspension layout with a patented i-Track idler pulley, maximizing pedaling efficiency while maintaining downhill performance. Constructed from MS3 stainless steel, our frames offer exceptional strength and corrosion resistance, retaining their polished finish even after years of use. With thin-walled tubes tapering to substantial thickness at weld joints, our frames weigh as little as 8 lbs for the average rider.

Our modular shock plate system allows for adjustable travel and progression, catering to both trail and downhill riding on a single platform. Enduro bearings and IGUS bushings ensure smooth rotation at all joints, with replacements available directly through us.

Custom frame geometry is integral to delivering the optimal ride feel and fit, with a range of options available and further customization offered through consultation to ensure the perfect fit for every rider.
