5DEV RGXC Titanium Crankset - 122mm Axle - Raw

5DEV RGXC CRANKSET

CNC-machined and laser-welded using an exclusive robotic system developed in San Diego, the RGXC titanium crankset redefines the standards of the discipline. Quite simply, it is the lightest and stiffest BMX race crankset on the market.

For more than two decades, the BMX standard has revolved around a 24 mm pinch bolt design with a steel spindle. A bulky solution endlessly copied and mass-produced, with no real innovation. Between aluminum spindles often too fragile for pro riders, a severe lack of serious alternatives for younger riders, and oversized Q-Factors reaching up to 175 mm, the market had stalled. The RGXC changes the game completely.

Record-Breaking Lightweight Performance, Proven Strength

• At only 516 g (including spindle and spider), the RGXC delivers a spectacular weight reduction, weighing up to 450 g less than the most popular competing models.
• - 29 mm 7075 Aluminum Spindle: Inspired by the extreme demands of DH racing and Red Bull Rampage, it guarantees absolute stiffness.
• - Elite Approved: Tested, pushed to the limit, and approved by the world’s top riders: Romain Mahieu, Rico Bearman, and Nic Long.
