Developed with input from Factor Racing athlete and 2025 men’s Gravel Earth Series overall champion Magnus Bak Klaris, SIXTY FOUR is engineered for the fastest gravel courses, where aerodynamic efficiency now matters as much as traction and durability. Its 64mm rim depth is a direct response to the use of larger-volume race tires. Wind-tunnel development showed that, as gravel tires increase in width, the wheel must do more work to manage airflow around the complete tire-and-rim system. The deeper section helps recover aerodynamic efficiency while supporting the control and confidence made possible by wider rubber.
A 30 mm internal rim width accommodates tires up to 57 mm (2.2 inch), increasing contact patch, traction, and stability across broken surfaces. Ceramic bearings and instant freehub engagement preserve efficiency under load, while the wheelset’s reinforced gravel construction is designed to withstand rough lines at race speed.
Paired with ELARA, SIXTY FOUR is not an accessory. It is part of the performance architecture: a deep-section gravel race wheel built to hold speed when large tires, rough surfaces, and decisive moments converge.
