Mavic XM 819 Rim

DESCRIPTION

We build lots of wheels, and the Mavic XM 819 Disc rim is a favorite of our wheelbuilders. Part of the appeal is that it's easy to build. Strong rims usually are. But the greatest appeal is that we can build a set and then forget about them. They're that reliable. We have yet to see one fold, or get reports of one taco-ing. For our customers, they definitely like that the rim comes drilled on only one side -- meaning it's tubeless ready without rim strips. The Mavic XM 819 Disc rim comes in black and is drilled for 32 spokes. You must install the m9 nipple holders along with the spoke nipples before building up the rims.

Strength:

Quite strong, tubeless, cheap

Weakness:

Narrow internal width, a little on the heavy side.

This was a pretty revolutionary rim for some time..... maybe not so these days but compared to some of the junk that's being put on mid-range bikes costing thousands of dollars it's seemingly still a great wheel.
I had one of these built up in about 2003 with 32 spoke and XTR hub. Haven't touched a thing in over a decade.
I'm typically between 210-220 pounds and can be known to be hard on my stuff.
I just outfitted my new to me used bike to XM819's because I didn't see the point in selling them on my old steed.....
Call me crazy, sure but what works isn't supposed to be messed with.
These are a strong all use wheel. You know your riding style. If you're breaking these it's time to stop complaining and either take some tips on how to ride lighter, do less drops on offset trails or upgrade to an Enduro/AM or Downhill wheelset. It's not always the equipment's fault.

Strength:

Worked well for the first 2 1/2 years of ownership.

Weakness:

Spoke nipple grommets corroded and pulled out of the front rim making the rim useless. Purchased a new one. One ride later the same thing happened to the back rim. Just out of warranty.

It's a shame that one small component failure of this rim makes the rim useless. Mavic doesn't seem to care based on their lack of concern since the rims were out of warranty. I won't buy mavic products again and will recommend to my fellow mountain bikers that they reconsider other rims for their riding needs.

Strength:

UST tubeless.
Very strong wheels.
Rim tape is not required.

Weakness:

Premature failure/corrosion.

Mavic customer service.

When I first got these rims, I would have given them five Flamin Chilies. Now that I had some time to ride them and they've had time to age, I lean to the other extreme and do not recommend these rims or Mavic products.

My wheels are out of warranty but in excellent condition. One wheel developed a leak which I thought was a tire leak. I added sealant and it still leaked. In could hear air escaping near the valve stem so I bought new stems. When I went to replace the stems, I found a corroded pinhole that breached the rim and was leaking air. This spot was near the valve stem on the smooth surface where rim tape would be on traditional wheels. There were four or five other spots around the wheel in a similar location. These wheels had never had sealant in them (until this leak) now has ever been touched with a tire tool.

I contacted Mavic to see why this may have occurred. After reviewing pictures, they could give any indication of why it failed the way it did. Although the rims were out of warranty, I atleast expected that they would offer and replacement rim set at a discounted cost. They offered nothing.

The wheels should have never failed in this way. After searching the web, I've found multiple reports of internal corrosion, mostly blamed on sealants.

Strength:

They roll. Seem pretty sturdy, at least for my riding. Have been hit by rocks but so far, only scratches.

Weakness:

Proprietary design and now (Sep. 2014) almost impossible to get parts for. Special tool required to replace spokes and that tool also seems to be just about impossible to find.

Before I got my Yeti bike, I had dreamed of getting the Mavic 819 Disc wheels. I thought they were the standard rim manufacturer. Now that I have them, (they came on my bike) it's more like a nightmare! I break spokes, I think most aggressive riders do. What I've learned about replacing spokes on this wheel is that whoever designed these wheels was more interested in post-sale service revenue than building a quality product. No bike shop anywhere in the Denver area that I've found has the exact same diameter spoke that my wheels are built with. They are thinner than what I can find. So, now I have a mismatched bunch of spokes on my wheels. The 2nd and also infuriating issue with these wheels is the proprietary M9 nipple adapter. You need a special tool to remove that, one that no bike shop around me sells either. What a screw job! So, either I pay the bike shop some stupid amount of money to replace a 50 cent part that takes about 5 min to replace, or I have to use the wrong wrench to remove the M9 adapter and install another odd sized spoke & nipple to ride my F'n bike! I could not overstate how much I hate Mavic right now! I've searched their web site and NOTHING comes up for "M9". This isn't rocket science. A rider should be able to easily purchase parts for a bike wheel of this age for many, many years. And it shouldn't cost an arm and a leg for such measily parts. If this ends up forcing me to replace my entire wheel, I can assure you it won't be a Mavic. Unfortunately, this is becoming very common in the mountain bike business. I don't know why, but the bike companies seem bent on forcing people to take their bikes to a shop rather than fixing even minor crap like this themselves. I'm not a happy camper, not at all. Next bike I buy certainly will NOT have Mavic rims on it.

Strength:

Not too expensive, look good.

Weakness:

Weak, easy to ding and buckle, heavy, difficult to build, doesn't work that well with Schwalbe tyres.

Very disapointed with these rims. Bought the XM819 to replace a cracked ZTR Arch (rider error). Rode the Arch for a year and a half and had only a few dings and buckles. After 5 weeks on the Mavic XM819 i've had to straighten 3 times and remove 4 or 5 dings. Riding the same trails, I've had more buckles on these than any other wheelset (including my superlight Shimano XTRs).

If you are after a strong, light rim, look elsewhere.

Strength:

Good reviews from most riders

Weakness:

Weak

I haven't ridden these very hard nor for many miles and they already have two dings one of which is major. I run tubeless and higher than most tire pressure, 35-38 psi. I had the Mavic crossmax slr set and the rims on that set were stronger. I'm just not impressed at all. I will not buy mavic again.

Strength:

Haven't ridden them long enough to know

Weakness:

Some of them rattle like a penny in a tin can.

Apparently Mavics are known for a manufacturing defect, that I wish I had known about before ordering these rims and building wheels. My rear wheel was built with the new Alfine 11 hub and the XM819 rim. At first I thought the noise was from the hub, but after close inspection, I detected that it was coming from the rim. I was told by several friends (after the failure) that Mavic inserts pins into the rim to align the sides before welding, and some of these pins come loose and rattle around.

I was unlucky with this rim, but Mavic is doing a warranty repair, replacing the rim and rebuilding the wheel. I can only hope that these rims do not start rattling in the future, especially after the 2 year warranty expires.

I give it 3 chilis, only because I am getting warranty coverage. Without warranty, it would be one flaming chili up the sphincter.

I have owned this set of wheel for 4-5 years now, I've used them on a tour from China to Iran in 2009. a great set of wheel, thinking of upgrading to the EX823 and a Rohloff for the next setup.

Strength:

Stiff

Weakness:

Maybe too stiff

I was changing my tire when I noticed on the inside of the rim by the valve stem hole that my rim is cracked length wise about 7"

There is no other damage to the rim. No flat spots or dings so I have no explanation how this could of happened. This is a pretty expensive rim for this to happen.

Strength:

Super Stiff, True tubeless UST that uses a collar system to hold the spokes/nipples in place. Never replaced a spoke. Only trued twice.

Weakness:

Sometimes rocks scratch the black paint...

Great affordable wheel-set. I used XT hubs and tipple butted spokes for disc brake use. I put a pretty good flat spot in my rear wheel after after a failed attempt at bunny hopping over two squares of sidewalk under construction. Even after the damage the wheels still hold up fine.

Use a triple butted spoke for added strength and weight savings. Have a professional mechanic build the wheel and bring it back after 10 miles of riding for a check up. After that it should be smooth sailing and you will only need to true wheels after extreme abuse.
