SEKA SPEAR BOREALIS BLUE FRAME

Description

SEKA SPEAR – a race-grade carbon aero frame

The SEKA Spear (Standard) frame is a modern aero-race road bike design, engineered for cyclists seeking high performance, excellent aerodynamics, and reliability in daily training and race conditions. The Spear model shares key design features with the RDC version, offering them in a more versatile and affordable configuration.

🧠 Design and Materials

• High-quality carbon fiber – the frame is made of advanced carbon laminates with an optimized layer configuration, ensuring an excellent balance between stiffness, weight, and durability.

• True-One-Piece Molding Technology – a monolithic frame molding process that eliminates traditional section joints, thereby enhancing structural integrity, fatigue resistance, and power transmission efficiency.

• UCI Approved – The frame meets UCI requirements and is approved for federation races.

🌪️ Aerodynamics – The DNA of SEKA’s racing models

• Wind Eye Design – a distinctive rear triangle design that improves airflow around the wheel and reduces turbulence.

• Aerodynamic tube profiles optimized using CFD methods, delivering tangible benefits at higher speeds, both in racing and during dynamic training rides.

• Fully internal cable routing, which improves the bike’s aerodynamics and overall appearance.
