The SEKA Exceed RDC is crafted using high-modulus carbon fiber and a refined layup process, resulting in a frameset that weighs just 898g (Charcoal Matte Black, M Size). This makes it significantly lighter than the standard Exceed model. The aerodynamic frame design, inspired by NACA airfoil profiles and optimized through Computational Fluid Dynamics (CFD), ensures minimal drag and enhanced crosswind stability.
Features & Benefits
- UCI certified
- Integrated Aero CockpitA one-piece handlebar and stem system with a -8° angle, available in 13 size combinations, promotes full internal cable routing for both mechanical and electronic drivetrains.
- Asymmetric Transmission Structure (ATS): Strategically varied carbon layups in high-stress areas like the bottom bracket, fork, and chainstays enhance lateral balance and power transfer efficiency.
- Functional Geometry System (FGS): Developed in collaboration with experienced bike fitters, the geometry offers a taller stack height, reducing the need for spacers and improving front-end stiffness and responsiveness.
- Compliance and Comfort: Despite its stiffness, the frame provides a comfortable ride, effectively absorbing road vibrations, making it suitable for long-distance rides and varied terrains.

Got the Seka Exceed RDC from underdogs and I must say the product and the impeccable service have EXCEEDED my expectations. I have never had such good communication and help from a seller every step of the way. The help didn’t end with the frameset purchase. They helped me source wheels, cranks and more as well. This allowed me to complete my first custom road bike build without any hiccups. The bike absolitely rips and let’s me keep up and go faster than all my dentist friends.
Highly recommended working with underdogs!
