BREAKOUT INTEGRATION

To create the fastest XC race rocket the world has ever seen, you've got to think a little differently. From its asymmetrically offset rear triangle and drivetrain to its new-school geometry and custom offset Lefty, every part of the new F-Si was designed as a System, fully Integrated in the pure pursuit of speed.

 

F-SI IS:

• A fully System Integrated approach to race-winning speed.

 

• Designed with the unique Ai offset rear triangle and drivetrain for category-leading efficiency, traction and clearance.

 

• The best handling 29'er hardtail in the world, thanks to the custom offset Lefty and System 29 geometry.

 

 

ASYMMETRIC INTEGRATION (Ai) DRIVETRAIN 
Our Ai design shifts the drivetrain and rear triangle to the right by 6mm. This creates an ultra stiff rear wheel by reducing dish, and delivers the shortest chainstays on the market, dual chainring compatibility, tons of mud clearance, and a super responsive rear end.

 

 

BALLISTEC CARBON
Our proprietary carbon construction method pairs ultra strong military armoring fibres with high strength resins and a tightly controlled network of high-modulus stiffening fibres to deliver ultra light frames with exceptional strength and ride-feel. Oh yeah, and lifetime warranties.
