A Cold-Blooded Slayer of Trails

Why We Love It
Behind the covert aesthetic lies a quiet menace and a very particular set of skills. The Assassin is a progressive gravel bike with a massive breadth of capability and compatibility. Its adjustable geometry adapts the handling to your specific theatre of operation and load-out, whether you want to race, explore, tour or shred. Drop off the grid with a bike-packing set-up, run reconnaissance on new trails, or go loud and rip up rougher terrain than you ever thought a gravel bike could handle.

The Assassin’s flip chips are the keys to your personal confidence. Rider preferences on bike handling vary and gravel trails vary even more, so one size does not fit all. Long and Low = rugged terrain, more MTB feel, likely on ≥45mm+ tires. Short and High = milder gravel, more road bike feel, likely on ≤38mm tires. Go shorter for more agility, go longer for extra stability, or take the middle option if you want a balance of each.
