Optimal frame and component integration delivering aero advantage and simplicity

Kú Cycle delivered with the TF1 a complete redesign of the front of the bike that showcases a striking aerodynamic fork and head tube tucked between the rider’s arms, which literarily opens up the entire front of the bike. It was only logical to search the market for the most advanced component partner that would integrate perfectly with the TF1 and to deliver maximum aero advantage. This led us to a simple decision: SRAM.

Modern bike design is moving towards greater integration of the frame, the components and systems. ‘Integration’ however is often misinterpreted as hidden; hiding cables and wiring regardless of the efficiency and convenience of doing so. Complex hidden wiring and cable systems are difficult to maintain and service. Breaking the bike down for travel becomes a process requiring deeper technical skills.

The more complex the system, the greater opportunity for failure; damage during build or breakdown of the bike, additional areas for wear and tear in use, wires chafing through if not secured properly.

Simpler systems are easier and more efficient to integrate, making maintenance, servicing and travelling equally simple. 

SRAM AXS system offers world leading wireless functionality, totally eliminating a complex wiring loom running through the frame. No independent battery to mount and access for charging on the frame. Updates for functionality can be made to the system by the AXS app.

SRAM are pioneers of 1x drive systems which sees an increasing number of followers in the triathlon community. 1x systems offer further simplification, eliminating the front derailleur and the potential aero gains of doing so.

The Kú TF1 is compliant and has been tested with major component manufacturers and we can provide a component spec for customers who wish to build their Kú TF1 with other brands. As a small start-up company, we love (and need) to focus really hard on what we believe delivers true athlete performance.
