Keeping up with the times.
Mavic's Ksyrium line has been nearly without reproach since it was created, but recently, all but its most loyal fan base have wondered whether the French brand was refusing to acknowledge the industry-wide move toward wider rims or was just falling behind. Dedicated Ksyrium users and casual observers alike will be interested to hear that the entire Ksyrium line was updated this year, and a new addition was added to the group. The Ksyrium Pro Allroad Disc Clincher Wheelset is ready to embrace the off-road gravel trend. It was designed to replicate the responsiveness and dependability the line is known for with a gravel-friendly, 19mm internal rim width to firmly silence any talk of the brand refusing to innovate.
Mavic offers the Allroad Disc in a 25mm and 28mm version, both of which offer improved traction for rough roads and packed trails. The wider tire platform also reduces rolling resistance for a more efficient ride. Mavic's concern for rider safety informed it's move toward wider rims, and it recommends using tires 25mm or wider with the Allroad Discs.
To construct the milled rims themselves, Mavic uses its Inter Spoke Milling 4 Dimensions (ISM 4D), which involves machining non-essential material from the rim to reduce weight, but keeping it around the alloy spokes to give the rims the strength and stiffness you'd expect from anything in the Ksyrium line. This process also lowers the rotating mass of the wheel for better responsiveness and acceleration than non-milled rims — making sure these wheels stay snappy in power-sucking loose gravel or on poorly maintained side roads.
The rim width wasn't the only part of the Allroad Disc that Mavic decided needed an update — the brand also reworked its hub design, introducing the Instant Drive 360 freewheel system. The system replaces the formerly used pawls with two interlocking, ratcheting rings that Mavic claims engage every nine degrees. In addition to faster engagement, the hubs are now easier to maintain and protect, especially after being treated with a new sealant to keep out moisture and debris.
Mavic includes a variety of adapters with the Allroad Discs to allow you to customize both front and rear to whichever rotor setup you prefer. The wheels come with quick-release skewers for the front and rear, and they're convertible to almost any diameter and width standards. You'll also receive a set of Mavic's Yksion tubeless gravel tires with the Allroad Discs, though you can choose to run them as standard clinchers if you prefer.
While they aren't bombproof, the included Yskions are quick on pavement and consistently stable in off-road conditions without being weighed down by aggressive knobs, and Mavic seals them to help resist flats. As a final touch, Mavic seals the rims of the wheels, so if you go tubeless, you won't need to worry about using any tape.

Are these compatible with my new 2017 Roubaix Elite? According to Specialized web feeds, I need 12x100mm thru axle up front and a 12x142mm thru axle in the back. Then there is the question of thread depth or thread gauge?? Help!
I bought a pair of these used and they are set up for I think 15mm thru axle in the rear. I need to switch to QR. I was able to do the front, but have no idea what is going on with the rear. Has anyone gone from thru axle back to QR on these?
UPDATE: took to LBS and they removed with vise. Very easy. Didn't charge me either.
I actually went the other direction but you just need to, carefully, remove the black cylinders at each end. They have a rubber o-ring on the inside with is why they are tight but you just need to get a good grip on them and rotate/pull them off. Afterwards you'll be able to replace them with the caps that are specific for QR.
Does the wheel set come with both 12mm and 15mm front hub adapters? If not, are the adapters available here?
Hi Thomas, the optional adapters for 15mm would need to be purchased separately.
Lightweight Wheels For Clydesdales
- Familiarity: I've used it several times
These are lightweight (1620g sans tires)
Freehub engagement immediate
Included tires (28c) are fast rolling and comfortable
Finally a wide-ish rim from Mavic!!!
Spokes are Mavic specific = less easily replaced in a pinch
Free hub is only supposed to be used with cartridge cassettes
28c tires are not tubeless ready w/ minimum pressure of 78psi (what's that all about?!)
Only wide-ish at 19mm internal width
So I was out riding a warm-up with my wife, the day before a century ride when I, again, broke a spoke on my Stan's Grail rear wheel. I was learning the hard and stressful way that my wheel set was designed for riders at least twenty pounds lighter than me. Stranded at a local bike shop that had been a mile from the breakdown, I began looking at the Allroads, and my wife noticed, and kindly ordered the wheel set for me while I worked on building my Grails again... The old wheels made it through my century ride, and the Allroads arrived a couple days after. It's worth noting that the rear comes with 9mm quick releases on and the front comes without caps on, requiring threading on your choice of caps.
At 1620 grams, this wheel set is right in line with its price range. Somehow Mavic has also injected them with Crossmax durability and stiffness. The Grails by comparison, are about half as stiff, visibly twisting and wobbling over bumps and in turns.
The tires Ksyrium Elite 28c are smooth and fast rolling. On my first ride with these tires, I was throwing rooster tails from both tires. By the end of the ride the tires were acting as tires should, offering a pretty low rolling resistance per the butt dyno and plenty of grip in the corners. I would purchase these tires again! Only I won't... Because they aren't tubeless capable. And how can that be when these wheels are perfect tubeless by design. No tape, no fuss. And for all that, somehow the matching tires aren't tubeless? I guess I'll be trying out Schwalbes when these are worn out. In the meanwhile I hope I don't get a flat since I really like the pretty black stems that we get with Mavic tubes! Only benefit that comes with not being tubeless I suppose.
All in all, these are a great system, and I'm happy to have them. I love the overall design and the bladed spokes are gorgeous!
As a short aside, as a Clyde, I guess the weight weeny stuff really isn't for me anyhow, but there seems to be this imaginary ideal (1500 gr) that people complain if their wheels outweigh. It's nonsense. Light wheels are great as long as they are functional and strong, useless if they are flexible and weak. Seriously, this number should mean less than the tech and function of a good wheel set. This is that wheel set. It should be noted that the Ksyrium Pro Disc wheel set is 1535 gr. But this means that for 85 gr you get a narrower and not tubeless rim. Everything is a balance.
The rear freewheel is a little tricky to convert to 12MM thru axel, the parts are included for a full conversion but there isnt any Mavic documentation referencing switching from QR. The rear hub does not have any hex key points, or flat spots for using a cone wrench. Its very strange. Send help.
Joseph, I had a hard time with this myself. If you have an axle vise, this is the best way to do it. The caps are held on by a small internal ridge. There are NO threads. If you don't have any special tools, I took an old QR axle and a deadblow hammer. Put the QR axle through at an angle (where it won't come through the other side, but rests on the inside) and give a good whack or two. This should do the trick.
Getting the 12mm conversion caps on is a bear as well. I have a homemade headset press I used for this and it worked like a charm. Good luck!!
If you run tubeless tires 38 - 41 mm for gravel, what is the recommended tire pressure? I saw a 2011 chart that said 88 psi. That seems extreme for tubeless and for a 38-41mm width tire.
It really depends on the tire. Traditional cyclocross tires typically run 30-50psi for tubeless. If you are running a semi-slick, you could run upwards of 75psi. Check the tire manufacturer for exact pressures.
