Project Speed
Project Speed
Project Speed is the R&D lab behind every Nº6 rim — one carbon supplier, one mold philosophy, one layup standard. The result: wheelsets that hold their line at 70 km/h and climb at 1.043 g.
Each model is wind-tunnel mapped, laser-aligned and hand-laced in low-volume batches — the soul of a custom build with the consistency of a pro-team supplier.
