Seka ExAero GR RDC Frameset - Born to Race - An Aero Gravel Frame
The EXAERO GR is no "play-it-safe" all-rounder. It's a race machine with a singular purpose: dominating complex terrain at absurd speeds.

Conquer without fear, defy the brutal surface. Speed is the Edge, Born to Win!

ExAero GR is no compromise for mere versatility. It is born for the race, where every curve is sculpted for speed and every claim is backed by precision testing. Developed through a comprehensive analysis of terrain conditions in premier gravel races, alongside athlete caloric consumption and storage volume requirements. ExAero GR harmonizes integrated storage, expanded tire clearance,systemic aerodynamic profiling, and lightweight.The Gravel Racing frame has now been redefined.

Massive Tire Clearance: 56mm Front / 52mm Rear
The ideal width is not a fixed value but should be tuned to specific course conditions. The ExAero GR accommodates this need with maximum tire clearances of 56mm(front) and 52mm (rear), giving riders the freedom to choose the optimal setup for any race or terrain.

Aerodynamics - Built for Real-World Racing
A gravel bike must master diverse terrains without compromising on speed and racing performance.When it comes to a frame’s racing performance, no factor is more critical than aerodynamic e?ciency.Our philosophy therefore focuses on the complete system’s aerodynamics in a real-world racing configuration. We optimize not just the frame’s drag coefficient, but the entire ecosystem: frame geometry, tire clearance, integrated storage, and modular expansion systems. In its optimal race-ready configuration, the ExAero GR delivers total aerodynamic performance achieves parity with the elite-tier road racing frame.

Wind Eye Design
The WindEye structure was redesigned and refined to meet the specific demands of gravel riding, offering superior structural adaptability for unpaved terrain. The seatpost achieves up to 16mm vertical movement with a rear vertical compliance of 106 N/mm, significantly enhancing vibration damping without compromising power transfer or lateral stiffness.

Integrated Internal Storage Compartment & Modular Mounting Interfaces
The integrated down-tube storage compartment, engineered to securely hold essentials like spare tubes, CO2 cartridges, and tools. The Fidlock magnetic latch, ensuring a seamless, secure, and clean interface that performs reliably in all racing conditions.Saves approximately 2.5 watts compared to a saddle bag of equivalent volume.

ExAero GR includes modular mounting interfaces on the downtube, top tube, and seatpost, providing maximum versatility for diverse race profiles. Additional dedicated accessories are currently under development.

Frame Weight 980g: Engineered for Gravel Racing
Lightweight design remains a paramount concern in SEKA’s philosophy, but never at the cost of overall performance. For a gravel racing frame built to conquer demanding terrain, we prioritize a robust structure with high stiffness and impact resistance—ensuring exceptional strength and durability without compromise. 980g (unpainted frame) figure represents the optimal equilibrium between lightweight performance and high impact strength, achieved through rigorous optimization and testing. TORAYCA® T1100G and M46J offer significantly higher tensile strength and fracture toughness. This enables the frame to maintain a high stiffness-to-weight ratio while substantially improving impact resistance and energy absorption capacity.

The ExAero GR comes only in our RDC Lightweight edition.

*Unpainted frame weight (980 ± 35 grams) for size 54, excluding paint and hardware.*Weights vary by colorways.

True-One-Piece Molding Technology
No joints, no bonding. Compared to multi-section molding or tube-to-tube bonding, the core advantage of the monocoque process is its continuous load path. It maximizes stress-bearing capacity and allows the carbon fiber to perform at its full potential.

This structural approach delivers superior overall stiffness and power-transfer efficiency while significantly enhancing impact resistance and fatigue life. This forms the foundation of the ExAero GR’s exceptional strength, durability, and long-term reliability.

6 Frame Sizes - Balancing Agility and Control
The ExAero GR’s geometry is engineered to strike an optimal balance between agile handling and confident stability on rough or loose terrain. It is available in 6 frame sizes and two seatpost offsets (0mm / -15mm offset). Trail maintained between 71 – 60mm (based on a 350mm wheel radius), which ensures direct steering feedback and predictable control during rapid line changes. A 74-70mm bottom bracket drop and 423mm chainstays working in concert with a wheelbase optimized for trail balance, these dimensions deliver both sharp acceleration response and unflappable composure.

SEKA Gladius G2 Fully Integrated Handlebar (Included with the frameset!)
The Gladius GR is an integrated handlebar system engineered specifically for the ExAero GR. The drops feature a 16° outward flare on each side, which optimizes wrist ergonomics for comfort while significantly enhancing control and stability on technical terrain. A slight backsweep design increases the forward reach space. Furthermore, the top section incorporates a micro-textured, anti-slip surface. This ensures a secure grip in wet conditions or on rough surfaces, providing confident control and stable front-end handling.
