Let them go.
Despite all the advanced technology and convoluted acronyms and initialisms on the Crossmax SL Pro LTD WTS 29in Wheelset's spec sheet, Mavic's top-end 29er XC wheel has one very specific job: to go really, really fast. Few entries on that spec sheet play as large a role in its ability to accelerate and hold speed across varying terrain as Mavic's Inter Spoke Milling 4 Dimensions (ISM 4D) process. ISM 4D removes excess material in targeted areas so as not affect durability, netting a lower rotational mass and reducing the wheel's tendency to remain at rest. Less inertial resistance means more forward progress. These wheels want to go. Let them.While Mavic's ISM 4D is responsible for keeping the rim weight down, the Instant Transfer System 4 (ITS-4) rear hub ensures that all that low-weight efficiency isn't wasted by sluggish, unresponsive engagement. IST-4 is a four pawl system that alternates engagement between two pairs of pawls. Since both pairs engage at different points in the freehub's rotation, the gap between engagement points falls to just 7.5 degrees of free play.
This nigh-immediate engagement is nice for sprinting in finales and while jockeying for position in mass starts, but it really makes its butter on technical climbs that require you to pick through trail furniture and pop over rock gutters. It's hard enough guiding 29ers across this kind of terrain as it is, so the extra precision is definitely appreciated. The sharp engagement angle is further complemented by the stiff, 17mm monoblonc axle, which tapers down to 12mm to take advantage of the new, more efficient standard of oversized dropouts.
The Crossmax SL Pro LTD WTS system is finished with Mavic's new Crossmax Pulse tires, which combine a dual compound build with a fast tread pattern that provides a bit more clearance for mud and debris than the typical hard pack-only XC tire. The center strip is built for unyielding speed, though the option to run the Pulse/Crossmax setup tubeless helps to soften the ride a bit. The shoulder knobs are a softer durometer for confident, consistent grip while leaning through fast corners.

No adapters for standard QR ?
Hi Gerald, the front wheel comes standard with q/r adapters, the rear has optional q/r adapters
Incredibly light, instant engagement
These wheels are excellent. They are very very light.
They also have a super quick engagement so power is transferred instantly. This really helps when accelerating to get over obstacles at slow speed.
The only downside- you will be using your brakes alot more as they roll down hill so fast you may get out of control quickly.
Can you ship Mavic wheelsets to Canada that are not on bike builds? Certain wheels are extremely hard to find if not impossible even at LBS's
Unfortunately we cannot ship Mavic outside of the US. If there is any other wheels that catch your eye, let me know and I'll look into shipping restrictions with different vendors. - Matthew Pizza - Expert Gearhead

Hands down one of the best buys in making your mountain bike faster. These non-carbon, 29er XC get the job done without breaking the bank. Mavic's top-end 29er XC wheels are light and stiff, the new Mavic ITS-4 Hub and its 4 pawl system is a great improvement over past generations. I used these wheels in Crusher in the Tusher, an 80 mile mountain bike race, featuring a near even split of tarmac and dirt/gravel sectors. I mounted 1.9âs on them and couldnât have been happier with my set-up. Only maintenance I have had to do is keeping the freehub body clean which is standard with any Mavic wheelset.
