The redesigned Open Pro rim utilizes Mavic's exclusive Inter Spoke Milling 4 Dimensions (ISM 4D), which significantly reduces weight and inertia without compromising durability. The smooth profile also helps by reducing aerodynamic drag, while the 19mm internal width accommodates 25-47mm tire widths.
The rim can be setup to run inner tubes or tubeless with UST valves, tape and designated tubeless tires. A tubeless setup provides comfort, improved rolling resistance and puncture resistance. Max PSI for tubeless setup is 87 PSI.
