The highest level of technology ever seen in a rim: ISM, UST, Fore, Maxtal. This 21mm asymmetrical rim is the perfect partner for riders looking for strong and versatil rims.
SUP: Stronger and smoother joint - Soudé Usiné Process. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish.
FORE: Stiffer and stronger - Instead of being drilled, the lower rim bridge is pushed on the inside, then threaded to enable the spoke nipples to be directly screwed in it, leaving the upper rim bridge intact.
Maxtal: Light and strong Exclusive to Mavic, this specific aluminum alloy offers a higher strength to weight ratio than conventional 6106 alloy.
ISM: Inter Spoke Milling. Lighter rim and equal rigidity is the magic equation to reduce inertia and to free extra power for climbing.
Valve hole diameter: 6.5 mm
Recommended tyre widths: 2.00 to 2.50
