Mavic Open Pro UST 28″ Rim

The Open Pro UST from Mavic is a tubeless-compatible 28″ rim made of aluminium with an inner diameter of 19 mm. Weight saving has played a major role in its development. The revised rim bed shape favours a quick tyre change.

Made exclusively for Mavic, this lightweight and strong aluminium alloy offers a higher strength-to-weight ratio than standard 6106 aluminium. Maxtal rims are 30% stiffer and weigh less than other aluminium rims.

SUP
SUP means Soudé Usiné Process and creates a much more stable and smoother rim joint. The rim joint is welded and then milled over to achieve an even braking surface. SUP prevents any brake judder and facilitates spoking and centring of the wheel.

ISM 4D
The ISM 4D (Inter Spoke Milling 4 Dimensions) milling process noticeably reduces weight and inertia without sacrificing durability. Mavic’s exclusive patent also provides better aerodynamics with its new rim profile. ISM 4D rims are up to 50 g lighter and therefore offer more climbing performance. Their minimal inertia leads to maximum acceleration. Their extra aerodynamic rim profile results in significantly lower air resistance.
