FiftyOne Bikes is an iconic brand based in Dublin, Ireland that is most famous for their custom, handmade road bikes. Just as every other brand has been swept up with the gravel scene, FiftyOne decided to jump in with their own production model – the Assassin.
We tested the bike (above) earlier this year – Fifty One Assassin gravel bike – and now FiftyOne is introducing a new colorway – black!
FIFTY ONE ASSASSIN GRAVEL BIKE
FIFTYONE BIKES is excited to announce the deployment of the Assassin Black Ops gravel bike. The Assassin Black Ops is available now as a frameset, and complete builds.
WHAT IS IT?
The Black Ops edition features black graphics over raw carbon fibre with a clear coat finish. It’s a cold-blooded slayer of trails; it speaks softly but carries a big stick. If your cover is blown and you need to change your identity in a hurry, the Black Ops edition also doubles as the ready-to-paint version of the Assassin, requiring minimal preparation before custom paintwork can begin.
COMPATIBILITY AND OPTIONS:
The Assassin gives total freedom of choice to build your bike to suit your riding and terrain:
• 47mm tyre clearance in both 700c and 650b
• 1x or 2x, up to 50/34
• Two front and three rear axle positions
• Dropper post and Di2 jointly compatible
• Front dynamo internal routing
• Fender and rack mounts, front and rear
• 4 portal bosses + 2 bottles
• Mild, Wild, Black Ops or custom paint
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.
