SEKA SPEAR RDC NIGHTHAWK BLUE FRAME

Description

📦 Availability and configuration

SEKA SPEAR RDC frames are available exclusively byspecial order.
Delivery time is approximately 3–5 weeks, depending on the selected configuration and availability from the manufacturer.

⚙️ Customization

When placing an order, you can customize key elements:

• selection of the length and width of the SEKA Rapier integrated cockpit,

• Choose a seatpost with or without offset,
  , which allows you to perfectly adjust the position to your riding style and body measurements.

🤝 Support and complete bike assembly

Contact us to help you choose the right frame size and configure your cockpit and seatpost.
We’d also be happy to build a complete bike for you based on the SEKA SPEAR frame, tailored to your expectations, riding style, and budget—from component selection to final assembly.

🧠 Top Racing Class – Engineering and Materials

The SPEAR RDC frame is an ultra-modern frameset designed for maximum performance, low weight, and excellent aerodynamics.

• Ultra-high-modulus carbon: The design utilizes a combination of TeXtreme materials and Mitsubishi PITCH 65T and 80T fibers (ultra-high modulus), delivering exceptional stiffness combined with low weight and high fatigue resistance.

• True-One-Piece Molding Technology – an innovative monolithic molding process without joints that maximizes structural integrity, reduces weight, and improves power transmission.

• Comprehensive CFD testing and wind tunnel testing at Aerocoach (Silverstone, UK) confirm real aerodynamic savings and lower drag compared to previous generations.

🏎️ Aerodynamics – a competitive edge

• Wind Eye Design – a distinctive rear triangle design engineered to stabilize airflow and reduce turbulence, thereby saving additional energy (achieving savings of up to ~2.66 W at 40 km/h compared to traditional rear triangles**).

• The entire frame has been optimized in a wind tunnel, resulting in up to ~6 W less drag than its predecessor (e.g., the Exceed), which translates to faster acceleration and higher speeds on flat sections.

⚙️ Detailed technical specifications

• Frame material: Carbon fiber – TeXtreme + ultra-high modulus PITCH 65T and 80T.

• Frame weight: approx. 685 g (size M, unpainted ±35 g) — an ultra-lightweight, race-ready design.

• Brake type: Flat Mount disc brakes, compatible with rotors up to 160 mm in diameter at the front and rear.

• Bottom bracket standard: 68 mm threaded BSA – a proven and durable system with high compatibility.

• Axle sizes:

  • Front: 12×100 mm thru-axle

  • Rear: 12×142 mm thru-axle

• Max tire width: up to 32 mm – offers a balance of comfort and aerodynamics.

• Drive compatibility: mechanical, electronic (including Di2 / wireless).

• Cable routing: Fully internal – for a clean look and maximum aerodynamics.

• UCI Approved: Yes – UCI certification allows for participation in federation-sanctioned races.

• Maximum rider weight: up to 109 kg/240 lbs (when fully assembled)

🛠️ Included components

The frameset comes with a comprehensive kit for building a bicycle:

• Frame and aerodynamic carbon top tube (fork)

• SEKA Rapier Integrated Handlebar (available in multiple sizes) – an ultra-aerodynamic cockpit constructed using monocoque technology.

• Front and rear thru-axle

• Spear Seatpost with a 0 mm or 15 mm offset option

• Handlebar set, adapters, and mounting hardware

• Standard derailleur hanger and Di2 battery adapter for internal mounting

📏 Geometry – Adapting to Your Riding Style

The frame comes in seven different geometries (5 standard + 2 racing), allowing you to perfectly tailor the bike to your height and preferred riding style (aggressive racing position or a more versatile one).
Sample specifications (size M):

• Reach: 379 mm

• Stack: 543 mm

• Length of the top tube: 534 mm

• Head tube angle: 72.9°

🏁 Summary – Who is this for?

The SPEAR RDC frame is designed for:

✔ Road and triathlon athletes looking for an aerodynamic advantage
✔ Ambitious cyclists who expect a high stiffness-to-weight ratio
✔ Those planning to build a professional-grade bike using top-of-the-line components.
