this Mavic SX 26” wheel set has never been used. Has some scuffs from storage in a dry shed, but otherwise as new. These came with a vintage Foes mountain bike I bought. Not sure if they ever had a tire on them, maybe the foes was sold with them and they swapped them out immediately? Not really sure. Perfect for vintage mountain bike restoration. These appear to be 2010 model.

100% seller and buyer rating, bid with confidence. Feel free to ask questions, but I don’t know much more about them.

From a review in 2010:

“The CrossMax SX from Mavic is their top of the line Enduro category wheelset. This wheelset is great for All-Mountain, Trail, and Park type bikes. The CrossMax SX sports Mavic’s top of the line features giving it strength, light weight, durability, and fast engagement.

Increased Internal Width: The internal rim width is increased for 2010 to 21 mm. This sets up a nice tire profile for aggressive riding.

Tubeless: The wheelset can be easily set up for tubeless (UST valves included with the wheelet) or traditional tubes.

Advanced Materials and Construction: The rims are made out of Mavic’s exclusive Maxtal aluminum alloy. It is an alloy that is used to create a lighter and stronger rim. The rim is constructed using Mavic’s SUP process. The rim is welded and milled at the joint to create a extremely strong bond. The construction technique also helps in making sure the rims are created with more precise overall balance.

Rim Weight Reduction: The CrossMax SX rims feature ISM which stands for Inter Spoke Milling. Each rim has the space between each spoke hole milled out to reduce weight while retaining the same rigidity. This allows the rim to have much less inertia for easier acceleration and braking.

Front axle size: 20×110 mm only

Rear axle size: QR (comes from the factory with QR adapters in place). Pulling out the QR end plugs converts it to a 12mm x 135mm thru axle. An optional 10x135mm bolt-in axle can be purchased as well giving this wheelset some great adjustability.

Instant Transfer System 4 – This system was designed for faster engagement using 4 pawls, working 2 by 2, giving the wheelset 48 points of engagement
