Inspyre Concorde v4 Frame - Purple Nebula

The Inspyre Concorde V4 represents the next evolution in high-performance aluminum BMX race frames. Developed and tested over more than a year with Inspyre Factory riders, the Concorde V4 delivers exceptional stiffness, precision, stability and power transfer for competitive BMX racing.

While Inspyre introduced its ERA CF carbon platform, development of the Concorde aluminum frame continued with the same commitment to performance and innovation.

Extensively tested by Factory riders Mathis Ragot Richard, Zian Lemee, Théo Thouin and Clément Rocherieux, the Concorde V4 has already proven itself at the Elite level, with Rocherieux securing his first Elite victory aboard a V4 prototype.

Built from premium AL66 aluminum with hydroformed, multi-butted tubing, the Concorde V4 combines advanced frame construction, optimized geometry and a completely redesigned rear triangle to maximize performance on the track.

REDESIGNED REAR TRIANGLE
The Concorde V4 features a completely redesigned rear structure engineered for improved stiffness, stability and power transfer.

The new rear triangle combines 3D-forged and CNC-machined components with a precision male/female dropout interface. The rear platform is now 12.5% wider, providing increased lateral stiffness, torsional rigidity and drivetrain clearance.

CNC-machined reinforcements optimize structural strength while minimizing unnecessary material and weight.

BB386 OVERSIZED BOTTOM BRACKET
Pro and Cruiser sizes feature an oversized BB386 bottom bracket platform measuring 46 mm in diameter and 86.5 mm in width.

This design reinforces the critical junction between the downtube, chainstays and bottom bracket, improving pedaling efficiency, acceleration and power transfer.

The BB386 platform also provides greater flexibility for modern crankset and bottom bracket configurations.

Smaller frame sizes utilize a traditional 68 mm BSA threaded bottom bracket.

FULLY INTERNAL BRAKE HOSE ROUTING
The Concorde V4 features fully integrated internal brake hose routing for a clean, streamlined appearance.

The brake hose runs internally through the top tube and exits directly at the seatstays, avoiding the bottom bracket area for easier installation, maintenance and replacement.

Pre-installed anti-vibration foam secures the brake hose inside the frame, preventing unwanted rattling and noise.

INSPYRE APEX CARBON FORK
The Concorde V4 comes equipped with the Inspyre Apex Carbon Fork, engineered for maximum stiffness, precise handling and efficient power transfer.

Its advanced carbon construction combines multiple carbon fiber types to manage lateral forces, torsional loads and impacts while maintaining a lightweight structure.

The fork features a high-strength 7075-T6 aluminum steerer tube and precision CNC-machined aluminum dropouts designed for a 20 mm thru-axle.

The aerodynamic fork profile is optimized to reduce drag while complementing the Concorde V4 frame geometry.
