Seka Spear RDC Frameset

Designed for the podium. Built for the relentless.

The SEKA Spear RDC (Racing Day Combatant) isn’t just an update—it’s a revolution. Developed from premium Mitsubishi Pitch fibers (65T & 80T) blended with TeXtreme, this frameset delivers an extraordinary balance of aerodynamics, stiffness, and ride compliance. At only 685g (unpainted, size M), it’s one of the lightest aero road frames on the market, yet it cuts through the wind with precision.

Wind tunnel validated.
SEKA’s in-house testing shows the Spear RDC saves 6 watts over its predecessor and outperforms the Specialized Tarmac SL8 in drag at yaw angles. The unique “Wind Eye” cutout on the seat stays alone saves another 2.66 watts at 40 km/h, while increasing vertical compliance for a smoother, less fatiguing ride.

Key Features:

• Premium Carbon Layup: High-modulus Mitsubishi Pitch fibers + TeXtreme spread-tow fabric for ultra-high stiffness-to-weight ratio.

• Aero Tube Shapes: CFD-optimized and wind tunnel tested.

• Wind Eye Seat Stay Cutout: Reduces drag and adds compliance.

• BSA Threaded Bottom Bracket: Quiet, reliable, and easy to service.

• Full Internal Cable Routing: Clean looks, low drag.

• Tire Clearance: Up to 32mm (fits most modern all-road tires).

• Integrated Cockpit: Includes SEKA Rapier one-piece carbon handlebar and carbon seatpost.

Geometry Options: Choose from 5 standard sizes (XS–XL) plus 2 aggressive “Racing” sizes (MR, LR) for a lower, longer race position.
