FiftyOne Assassin Frameset DESERT STORM

WHY DID WE MAKE IT?

Because we love gravel riding and because we felt that we could use our vast experience of building custom bikes with individually-tailored geometry to bring something new and better to the gravel sector. We understand that every rider wants confident handling, and that the geometry required to deliver that feeling varies from one individual to the next.

FLIP CHIPS EXPLAINED

At the rear, two chips offer three axle positions, adjusting the effective chainstay length and overall wheelbase in 5mm increments. Go shorter for more agility, go longer for extra stability, or take the middle option if you want a balance of each.

At the front, the chips offer two positions, High and Low. The ‘Low’ position gives a longer trail and slacker head tube angle, suited to more aggressive riding on more challenging terrain; the ‘High’ position creates shorter trail and a steeper head angle, ideal for gravel races or rides on back roads and less rough terrain.

• Long and Low = rugged terrain, more MTB feel, likely on wider tyres

• Short and High = milder gravel, more road bike feel, likely on narrower tyres

• Experiment to find the combination that suits you and your riding best

Whereas some bikes seek to maintain a constant trail figure when switching from 700c to 650b wheels, that’s the exact opposite to our goal. The Assassin’s flip chips allow you to tailor the geometry and handling to how and where you ride. Having refined the geometry options so carefully, we then ensured that the crucial trail figures remain consistent across all frame sizes.
