FiftyOne Sika Frameset

High Performance for the Real World

The FiftyOne Sika isn’t just another aero road frame; it’s a masterclass in balance. Designed in Dublin by the masters of custom carbon, the Sika combines feathery lightness and razor-sharp stiffness with a "real-world" geometry that allows you to ride harder, longer. It’s a race-bred machine that doesn't demand you spend your life in a yoga studio just to reach the drops.

Why the Sika Stands Alone:

• Aerodynamics Without Compromise: The Sika features a sleek, aero-profiled design with fully integrated cable routing, saving you watts while maintaining the clean, minimalist aesthetic of a modern superbike.

• Massive Tire Clearance: While most road racers are capped at 28mm or 30mm, the Sika offers clearance for up to 40mm tires. This turns it into an "all-road" weapon, capable of transitioning from smooth tarmac to light gravel without skipping a beat.

• Integrated Carbon Cockpit: Each frameset includes FiftyOne’s custom one-piece carbon bar and stem. You choose your specific width and stem length at the time of purchase for a factory-fit feel right out of the box.

• High-Modulus Construction: Built from top-tier carbon fiber to ensure a complete build weight as low as 7.2kg, the Sika is a mountain-goat on the climbs and a rail-guided missile on the descents.

• Dublin Finished: Every frameset is factory-finished in Ireland, ensuring the paint and craftsmanship meet FiftyOne’s legendary boutique standards.

The FiftyOne Philosophy: "Sika" is named after the agile deer found in the Irish mountains. Fast, light, and perfectly adapted to its environment. This frameset is for the rider who wants a bike that excels on the Sunday paceline but isn't afraid of a rough backroad shortcut.
