Inspyre Concorde V4 BMX Race Frame

Inspyre Concorde V4 BMX Race Frame with Pride Apex Carbon Fork Available December 2026 The Inspyre Concorde V4 is a high-performance aluminium BMX race frame developed for modern BMX racing. After more than a year of testing and refinement with Inspyre Factory riders, the Concorde V4 represents the latest evolution of one of Inspyre's established aluminium race frames. Developed and tested by riders including Mathis Ragot Richard, Zian Lemee, Théo Thouin and Clément Rocherieux, the Concorde V4 has been refined to deliver a combination of stiffness, precision, stability and power transfer for competitive BMX racing. The frame kit combines an AL66 aluminium frame with an Apex Carbon Fork, creating a lightweight and performance-focused BMX race setup designed around efficient power transmission and precise handling. Redesigned Rear Triangle The Concorde V4 features a completely optimised rear structure using a 3D-forged and CNC-machined construction with a male/female dropout interface. The rear platform has been widened by 12.5%, increasing stiffness, stability and strength while providing additional clearance around the drivetrain. CNC reinforcement adds lateral support and torsional stiffness while allowing material to be optimised throughout the structure. On Pro and Cruiser sizes, the BB386 Ø46 mm / 86.5 mm bottom bracket platform strengthens the connection between the downtube, chainstays and bottom bracket. This construction is designed to improve power transmission and precision during acceleration, while also allowing greater flexibility when selecting compatible cranksets and bottom bracket configurations. Internal Brake Hose Routing The Concorde V4 uses fully internal rear brake hose routing through the top tube, exiting directly at the seatstays. The hose does not pass through the bottom bracket area, making assembly, maintenance and brake hose replacement more straightforward. An internal anti-vibration foam system is pre-installed to keep the brake hose securely positioned while reducing unwanted noise during riding. Apex Carbon Fork The Apex Carbon Fork is designed specifically to complement the Concorde V4 frame and optimise structural stiffness, energy transmission and handling. Its internal carbon construction uses different types of carbon fibres to manage lateral loads, torsional forces and impacts efficiently. The fork features a 7075-T6 aluminium steerer for strength and durability, together with CNC-machined aluminium dropouts for accurate wheel positioning. The fork is designed for a 20 mm front thru-axle. 20 mm thru-axle is not included. Built for Modern BMX Racing The Inspyre Concorde V4 is designed for riders looking for a high-performance aluminium BMX race frame with the stiffness and precision required for competitive racing. Its combination of hydroformed multi-butted aluminium tubing, a redesigned rear triangle, internal brake routing and Apex Carbon Fork makes the Concorde V4 a complete frame kit focused on acceleration, stability, handling and control.
