Mavic Crossmax SL Ultimate 25 disc 29 wheel set Boost 6 hole SRAM XD- freewheel

Lighter, stiffer, faster: from now on it's all about gold

With a weight of just 1340 grams, the Crossmax SL Ultimate is the wheel that performance-obsessed cross-country racers dream of. Mavic developed it together with top professionals who want real competitive advantages at World Cups and Olympic Games. And with its ultra-light 29 "carbon rim (340 g!) It guarantees lightning-fast acceleration and climbing properties without compromising on stiffness and durability.

"Adaptive Lay-up", a special carbon lay-up technology, makes it possible to manufacture these carbon rims by hand with less material between the spoke bores. The spoke holes themselves are reinforced with strategically positioned layers of carbon, so that noticeable weight is saved without compromising stiffness and strength. The lighter rim accelerates faster, climbs more efficiently and feels more agile on the trail. Your carbon top layer receives Mavic's new UD² finish and thus an exclusive look AND even greater durability.

Extensive driving tests with Mavic's professional athletes have shown that an internal width of 25 mm is ideal for light-footed, precise driving characteristics and optimized tire grip on fast racetracks. On more technical trails, some preferred a 30mm mouth width for more control. So Mavic developed both options. Now you have the choice and you can even mix the two - for example with a Crossmax Ultimate 25 as the rear wheel for faster acceleration and higher efficiency, plus a Crossmax Ultimate 30 at the front, which gives you more confidence and control on technical single tracks.

The carbon rims are spoked with 24 straight, double-thick spokes of identical length and crossed twice in order to achieve maximum power transmission AND better vertical flexibility. The new, lighter Infinity hubs increase the lateral stiffness, their lacing ensures optimal power transmission. Mavic's Instant Drive 360 freewheel with two tooth lock washers guarantees fast traction and high rigidity at the same time, so that you can accelerate faster out of corners.

Highlights

• Top climbing properties & faster acceleration: The new adaptive lay-up technology saves 70 g per rim. The 25 mm rim weighs only approx. 340 g
• Stiffness & smooth handling: Special carbon lay-up for superior rim stiffness and more control on descents. Double-crossed double-butted spokes for greater vertical compliance
• Efficient power transmission: New, lighter Infinity hub construction plus 24 straight spokes for optimized stiffness and better balanced spoke tension
