Mavic Crossmax SL 29'' Front Wheel | Boost 15x110 mm | 6 Bolts | 2021 Mavic

Crossmax: This name has a long history in the cross-country world, and the Mavic Crossmax SL 29 MTB wheel continues that heritage. Mavic technologies have proven themselves; this wheel puts a large number of them within reach of all budgets. Weighing in at just 1700g, it is truly versatile. This is the best aluminum alloy cross country wheel in its class.

The rims are manufactured using Fore technology, including a fully sealed upper deck, which eliminates the need for a rim tape. Each wheel weighs 30 grams less and saves the cyclist the need to install a rim tape before installing a tubeless tire. The rim is 25mm internal width, with a tough hookless profile, and Black Shield technology gives it a unique and modern visual identity while protecting it from scratches and abrasion.

The Crossmax SL uses 24 straight spokes (same spoke length throughout) to ensure a strong rim-hub connection and a balance between efficiency and durability. The special machining of the hub guarantees the safety of the spoke head, while allowing it to retain play, which allows the wheel to absorb shocks due to obstacles encountered on the way.

The + product:

• Better acceleration, better hill performance : sealed rims drilled using the Fore technique reduce weight and increase strength. More rim tape: 30g less per rim. High reliability ID360 instant engagement freewheel system.
• Increased traction and durability : 25mm wide hookless rim profile optimized to reduce tire pressure for better grip in all conditions. Optimized for cross-country tubeless tires from 2.1 to 2.3 ''. The Black Shield treatment protects the rim from bumps and scratches.
• Very easy to use tubeless system : the rim, completely waterproof without rim tape thanks to Fore technology, makes it easier to fit and change tubeless tires. The upper deck is not drilled, which helps to increase the rigidity and durability of the rim.

Technologies:

• Fore tubeless technology without rim tape : stiffer and more robust. Instead of being drilled, the lower rim bridge is pushed back on the inside and then threaded to allow the spoke nipples to be screwed in directly and to leave the upper bridge intact.
• UST Tubeless technology : Universal Standard for Tubeless traction and control. Ready-to-drive tubeless system. The UST system improves traction, control and comfort while reducing inertia and the risk of punctures.
• Instant Drive 360 Freewheel System : The new Instant Drive 360 freewheel system is ultra light and efficient. An oversized non-contact rubber seal reduces friction to a minimum, and a wide choice of adapters makes it compatible with all types of frames and axles.
• QRM Auto Automatic Bearing Adjustment Technology : Mavic Auto Bearing Quality Our latest innovation. These cartridge bearings are obviously double sealed, with C3 internal clearance. Their preload is automatically adjusted to ensure, in the long term, a perfect rotation without any play.
• Black Shield treatment (protection of the rim against shocks and scratches) : new treatment of MTB rims. Service life doubled against stone impacts and scratches.
• SUP welding technology : a more robust and smoother "Soudé Usiné Process" connection. After strapping, the rim fitting is arc welded. The welded joint is then machined to obtain a smooth finish.
