Product detailed description

SPK G4 Evo - Ultegra Di2

The Highest Stage of Development

The SPK G4 is the best road car Pardus has produced to date. Thanks to wind tunnel testing, there’s very little for the wind to catch on.
SPK G4 Evo - Ultegra Di2

The frame was aerodynamically optimized using CFD (Computer Fluid Dynamics) and tested in a wind tunnel

All frames are inspected using ultrasonic technology to detect hidden material defects such as bubbles or cracks.

State-of-the-art expanded polystyrene core technology with latex (EPS+) ensures a consistent, smooth wall and maximum resin extrusion for an ultra-lightweight result
SPK G4 Evo - Ultegra Di2

25% greater stiffness under pedaling force than the previous generation

By adjusting the carbon composition and incorporating a more robust center joint, stiffness has increased significantly for even better power transfer

New Frame-to-Fork Joint Reduces Turbulence

In previous generations, turbulence occurred in the gap between the fork crown and the down tube. The SPKG4 eliminates this issue.

The integrated cockpit cuts through the air like never before

The carbon monocoque with a flat, aerodynamic shape offers excellent handling and minimal deformation under load. It retains its ability to absorb vibrations while providing sufficient feedback to the rider’s hands.

The Pardus bike surprised me with its stiffness and aerodynamics. I regularly use a road bike from the same brand to train—not only for international events, where I rely on it completely.

Geometry

The SPKG4 is a compact aero road bike. In some cases, it may make sense to buy a frame one size larger than you usually would.
