    Crank Brothers Cobalt 3 29 vs Mavic C29ssmax 29er Wheelsets

    I'm looking for a light weight disc 29er wheelsetin the $900 range. I've norrowed it down to the Cobalt 3 29er and the C29ssmax. I want a wheelset with no holes in the rim so I can set it up tubeless using non UST 29er tyres with sealant. I'm 200lbs and mostly ride cross country on weekends. Does anybody have any experience with either of these wheelsets? Which one is stronger and stiffer and requires less maintenace? Any other recommendations besides these two?

    Also the Easton EA90 XCs. UST and weigh ~200g less than the Mavics.

    Well it's a quiet morning at work... let's spend some time replying...

    I bought a C29ssmax wheelset in October 2007 and still riding it. 1755 grams actual weight (830 front and 925 rear). I never had a broken spoke, only one that is slightly bent after it has been hit by a big rock. They never been trued. I changed the bearings in the rear hub but not in the front because I replaced the 9mm axle wheel with a 20mm maxle. Much stiffer, tracks better. The 9mm axle wheel is actually a 15mm hub with caps so there was a little lateral movement that I hated. So much that the spokes were rubbing against the Avid Juicy 7 front caliper. Problem solved when I bought Hayes brakes with narrower calipers. I've been successful to install and ride any non UST tires I had. (Bontrager Jones, Kenda Karma, Maxxis Ignitor, Schwalbe Furious Fred and Rocket Ron, Stan's the Crow, Kenda Small block 8). No leak, no blowoff, with two scoops of Stan's sealant.

    The only problem I had with the C29ssmax is the crappy plastic bushing installed in the original freehub (Mavic is getting a lot of hate in the posts because of that). It broke after a year. Fortunalety, my lbs replaced it with a new freehub body that has metal ring instead. No more problem since 2008. Cleanin and greasing the rear hub is the only maintenance I do mysef from time to time.

    I weight 185lbs. Unless your are looking for a superlight wheelset in the 1550-1600 grams range I think the C229ssmax leads the pack. Super strong, super stiff, silky smooth bearings, durable.

    I don't work for Mavic although my avatar shows a mad frog. I just really like their wheels.

    Sorry, but you are wrong. Until recently, Easton has posted that their weight is 1560 grams but if you go on the web site now it is written 1697 grams. Only 58 grams less thant the Mavics with likely smaller spokes than the fat-ass zicral (1560 is now the weight posted for the 26er wheelset...)

    the holes in the rim thing should be low on your priority list for tubeless conversion of non-UST tires.
    UST beads are not that great for converting non-UST tires. some people have success, many more do not. fact of the matter is that UST beads were designed for tubeless use with UST tires and for use with tubes with regular tires. Stan's rims are far better at converting regular tires, since that's what they were designed to do.
    and since you asked, for $900 you can get a lighter, more serviceable, stiffer, stronger wheelset with FAR better hubs and easier tubeless conversion of non-UST tires than either of those wheelsets. if you want to spend all that money, Chris King + Stan's Arch would fit the bill at about the same weight and be very strong. Hope Pro II hubs you could do for less money and they are lighter. Also, I weigh more than you do and ride 355's (lighter than the Arch) hard on rocky terrain at very low pressure with no complaints.

    can a 20mm maxle work in "standard" fork dropouts?

    No... he had to change forks, which added another variable to the equation, muddling the conclusion a bit.

    Also, according to Mavic, there was no 20mm TA C29ssmax prior to 2009. The one that is now available is not convertible to any other format. In 2009 Mavic changed the C29ssmax front hub to a design that is 15mm TA with end caps for 9mm q/r, so converting between the two is just a matter of removing the end caps.

    Menzo-
    I'm curious about your conversion, since it directly contradicts what I've been told by Mavic. Wouldn't be the first time a mfr got something wrong, but also having seen and worked on the hubs, I don't understand how you could convert any 9mm C29ssmax hub to 20mm TA... especially a pre-2009.

    Yes but you need to buy 9mm caps for 20mm hubs. Check that link...

    How do those plugs handle the spacing difference (110mm standard for 20mm TA vs. 100mm standard for 9mm q/r)?

    ok. now i'm totally confused. that looks like i would still be using a 9mm qr skewer.

    so if i want something more robust than a 9mm skewer but i have a fork with standard dropouts, is there anything i can do? (i mean other than replace the fork.)

    hi
    Ive been doing some research about wheels for some time as I wanted to upgrede my GF mamba, read some bad reviews about the CBs cobalt 29, althouhg its price ($~500/600), I wouldn t buy them. Had placed an order in CRC for fulcrum 29sl (less than $300) but cancelled my order after continuous "out of stock item" mails. Finally came up with shimano mt75 29 tubeless ($450), they arrive tomorrow, cant wait to test them!

    the short answer is that to change axle formats you have to change forks.
    a different type of skewer might help some (e.g., Shimano internal cam or DT Swiss RWS), but they are still going to be skewers, which actually have a diameter of 5mm (the 9mm is the outside diameter of the tabs on the hub).

    It's impossible. I sold the 9mm front wheel and replaced it with 20mm TA. However, going from 20mm TA to 9mm would be possible with end caps as it is possible to go from 15mm TA to 9mm with end caps

    How do those plugs handle the spacing difference (110mm standard for 20mm TA vs. 100mm standard for 9mm q/r)?
    That is a good question. I don't have the answer but I guess there is a way to do it.

    Otherwise, why is Mavic selling these 20mm to 9mm caps...

    Well I think the end caps are made only for the Mavic Crossline wheelset.

    You have to buy a new fork fab4...

    Except for the 100/110 spacing issue, which isn't a factor for the 15mm TA format.

    Fulcrum Red Metal 29 XL.

    Costs between a Mavic Crossmax 29 and a Easton EA90. Weight is the same as Mavic, but no questions with freehub bushes (like Mavic) or loose (like Easton).

    High end wheels performance and finish, trouble free and zero maintenance questions.

    This is a post right up my alley. I have both the crossmax and the cobalt 3 in my garage right now. I have put probably 500 miles on the crossmax and another 500 on the original cobalts. I sold the original cobalts this past sunday and I literally got the cobalt 3 on tuesday and have maybe 25 miles on them.

    As for the differences. The crossmax is a great feeling wheel it is stiff and agile. The cobalt 3 feels a bit lighter and a bit more lively. The cobalt feels like it just wants to get up and go whereas the crossmax feels like it wants you to start hammering away on it.

    As for durability, they are also a push so far. I never had any issue with the crossmax's or the original cobalts. I have noticed the Cobalt 3 does have a much quieter rear hub then the original which is very nice. I also believe Crank Brothers has addressed the bearing issue with the cobalt 3. The front comes in either a 15 thru or a 9mm qr, I do not see how the three can have the interchangeablility that the original cobalt did. I am okay with this update because the front hub seems to react quicker on the 3's.

    I only sold the original cobalts because I sodl the bike they were on. I personally like the cobalt's better than the crossmax but I feel they both are going to be a very reliable XC wheelset.

    FYI, with getting the cobalt #'s, I will have the Crossmax's up for sale within the next week.

    ^Way to contribute!!

    My boss who is a 350# weight lifter loves the c29ssmax wheels. The only problem he has had was a broken spoke, but that was his fault. I am around 300# and have prob 50 miles on my C29's. That are fast, stiff and light. They look great too!!

    Love my C29ssmax'es! Problem is, they are the pre-2009? model I think - as my front hub does not convert to 15mm TA... I took it apart and noticed it's different than the new style (from looking at the Mavic service pages - my LBS buddy had given me the link)

    Can the front hub easily be swapped? I'm starting to get irritated with my 9mm QR...

    I don't want to hi-jack this thread but the info I have to share probably doesn't justify it's own thread and any one looking for info about the Cobalts might be interested. I just got a new set of Cobalt 2's (29er version) yesterday and could not get the front to stay pumped up tubeless for more than a few seconds. I turns out the wheel has a couple of thin spots on the inner rim surface, one of which leaks air. After pulling the tire off the rim, and saving as much of my sealant as possible, the flaw was obvious even to my untrained eye. I know mistakes happen, but it really makes you question a companies quality control when an item such as this makes it to a customer. The company I bought from is being great about the replacement and the owner says he has sold several and this is a fluke, but I thought my experience may be note worthy. By the way, the Cobalts look incredible, I can't say how they ride yet.
    For what it's worth, my C29ssmax wheels have been flawless for almost 2 complete seasons, literally zero maintenance, aside from some cleaning and a couple of drops of oil here and there (195 lbs, aggressive Michigan trail rider).

    For that much, you are very close to a set of I9's. Save a few more $$ and get those, they are awesome!

    Or save some money and get a set of Stan's. Both of my sets have been awesome so far.

    Keep us update on how it works out. I was planning on getting a set of the Cobalt 3's since I'm not doing anything wild on my 29er. I've heard some bad things about the first version but haven't heard much since they updated the Cobalts.

    Update on my Cobalt 2's

    I finally got my replacement front wheel! Crank Bros. has had the defective wheel in their possession for 2 1/2+ weeks and has not contacted the retailer about replacement. So, my retailer had to pull a front wheel from his own stock to replace my wheel. I don't understand why CB is dragging it's feet on this, the wheel was manufactured with a large hole in the inner rim that leaked and made it impossible to air up tubeless. Common sense would say, replace the wheel to keep a customer happy and figure the rest out at their leisure, but no. Whew, sorry about the rant but I had to vent!! While waiting for my new wheel to arrive I moved my C29SSMAX wheelset to my new Spearfish to get a few rides in on the bike with a better wheelset, I put the rear Cobalt on my Stumpjumper to keep a rotor in the caliper. I liked the way the cobalt looked on the Stumpy, so decided to leave the C29SSMAX set on the Spearfish. Well, it turns out the Cobalt wheel will not work on a bike with Elixir calipers and a 160mm rotor, any turning resulted in the spokes heavily scraping the caliper, thank God my spearfish has a 180mm front rotor that allows the caliper to clear the wheel. You would think that somewhere in all that literature on their website Crank Bros. would have mentioned a compatibility issue. Has anyone else run into this problem? All the parts swapping between bikes chewed up my after work ride time, first ride will happen tonight I'll check back in tomorrow with a ride opinion. I really hope to have some good news to share because so far these wheels and Crank Brother's customer service have both been an enormous disappointment. (Guess I should have saved my apology for venting till the end, huh? )

    I use my cobalts witha set of avid elixir CR's and 160mm rotors front and back and have not had any issue with them at all. The spoke s and calipers have plenty of clearance room.

    Odd, the Elixir CR's are what I'm running. I can't think of anything that I could change that would cause the caliper clearance to vary. Maybe I'll try again (and take some pictures to post). I wonder if they machined the rotor face on the hub back to far.

    I am considering a set of C29SSMAX but am concerned about the rim width... I am going to be running them on a full rigid and want to have high volume tires (preferably 2.4 Racing Ralph or new MTN Kings). However, I really don't want to bust my ass in accident due to tire roll off/blow off! I am 6'5" 205 and ride fast aggressive XC in the SE.

    Thoughts?

    Many Thanks,

    PF

    *as a side note, I can pick them up for cost so I would love this to work!

    I had Mavics, Easton Haven and American Classic Tubeless sets of wheels at the beginning of the season. Mavics were to flexy and narrow. Running 2.4 on them will not only look funny, but may affect the tire performance. Ditched Mavics due to their flex mostly. Easton Havens were the stiffest set of 29 wheels I have ever owned. However - on the heavy side - at 1800g.

    Settled with American Classic - which was the best combination of stiffness and weight. Sold both Mavic and Easton and purchased another set of American Classics (dry tires on one set, wet tires on the other) and the combo is working to my utmost satisfaction.

    One of the most important factors was the rim width - 26mm for AC. You can run 2.4 easily on them without any fear of burping or rolling off.

    My weight is 195# @ 6'

    Hope this helps.

    Finally got to ride my new Cobalt 2's last night and all the troubles aside I'm kinda impressed. As it turns out the caliper interference problem is common with these wheels, using a 180mm rotor provided just enough clearance to make things work . Last nights ride was only 10 miles, but it's a decent blend of my local trail characteristics and these wheels felt great. Compared to my C29SSmax the Cobalts felt equally as stiff laterally and seemed to accelerate faster, as though they are stiffer under torque than the Mavics. Time will tell if they are durable but for $500 I don't know if there is a better option.
