    So I might be the first to have cracked an advanced 29er showing a 3" vertical line in the carbon with a spider on one side. It's between the bottom bracket and the upper pivot on the seat tube.

    Do you think that running a seat dropper post would help prevent these cracks in the seat tube/down tube junction? I figure that running a regular seatpost, I'd be more likely to make a higher force contacts than if I lowered the seatpost. I have a 6" AM bike that I ride in tougher terrain, and I am planning on building up this new Anthem 29er for XC races, so it won't be ridden in techy terrain. I was thinking about the 4 LEV.

    Re: Anthem X cracked frames.

    @smirniotisice, I too would like some good pics.

    ...and no, a dropper post will most likely not help in preventing a cracked frame.

    Re: Anthem X cracked frames.

    Nope. This is actually the very first one I've ever heard of. One of the main reasons I'm interested in pics.

    Re: Anthem X cracked frames.

    Well, I guess that goes to show that Giant is good on warranty replacements. All of the damage on the Advanced 1 frame on ebay looks like user damage and not a manufacturer defect.

    That is a very strange place for a crack. Not a lot of stresses right there I'd think.

    Discovered this Sunday. Had 20 miles left including a 3,000 vert feet dirt road descent to get home. Held together, could see it gapping (perhaps 1mm) when I was seated climbing. Giant is replacing the whole frame minus shock with a 2012. They don't have 2013 replacement frames in stock yet.

    FYI. Thought it ought to be out as a data point. I'm 190-200 lbs 6'1" often ride with a fairly heavy pack (100oz water, clothing, etc). I've put between 1200 and 1500 miles on it since getting it December 28, including 24 solo at Old Pueblo. I do ride tech trails but have been pretty cautious after getting hurt a couple times late last season. Definitely no hucking... Have not crashed it.

    Seems like Giant is responding quite quickly, although I don't know what the eta of the replacement is yet.

    Anthem X cracked frames.

    Giant was quite good with the frame replacement for me (although they refused to change the Anthem 29 frameset for a Trance 29, even if I was willing to pay a price difference).
    In less than a week a 2012 X0Anthem X cracked frames.-imageuploadedbytapatalk1367526222.985940.jpgAnthem X cracked frames.-imageuploadedbytapatalk1367526281.252353.jpg whole frameset arrived with a brand new shock. They rear shock mount seems to be the same design as my 2011 frame; I hope that this one doesn’t break.
    Here are photos of the crack and my new ride.

    can see that in this design the seattube will want to bow in due to combination of force on the rocker pivot and rider on saddle - ie both making the seat tube wanting to bow towards the headtube..

    flattened top tube will be doing little to help support the seat tube from flexing and looks like a rather nice hinge..

    this would explain the position of the cracks at seat tube/ top tube, centre of seat tube and a lower end..

    perhaps in the quest to save weight the seat tube is a bit thin..

    I have a Giant Anthem X2 replacement frame waiting for me and I have a few questions.
    Long story long, my father in laW cracked his anthem. After a a bit a back and forth, Giant agreed to replace the entire frameset included the shock due to the fact that the design changed quite a bit since 2007 and the front and rear triangles wouldn't be compatible. One huge point for giant in my book. Pops in law didnt want To wait for the replacement frame, so I have been given the new frame. Pretty nice of pops in law. However, nowhere can I find the specs off an anthem x2 frameset only. The colors are red and blue and then od2 headsetnis imcluded. I'm thinking maybema European orcas Asian markets frame. Or perhaps, giants follow treks example and painted replacement frames differently. ie treks raw alum replacents for black and blue and gray fuels.

    Thoughts ?

    There's no such thing as an X2 frame set. If it's an X2 it came as a complete bike, and you want to look at the X2 bike spec. They're simply replacing the frame like for like in terms of the shock included if it's spec'd as an X2.

    Well my post was quite full of typos! Thats what 24 hours shift do to your mind! I am thinking its the Anthem X frameset as sold overseas as a frameset only. I'm more curious about the color of the frame. I haven't seen a red and blue anthem anywhere on my internet searches. If its something out of the ordinary, I'll post a picture when I get it built up. It will most likely end up as back up bike. I can't imagine a full suspension will replace my beloved 853 steel hard tail.

    2011 x1

    Well went for a short ride yesterday, and my 2011 26er decided enough was enough (not like I'm and aggressive rider or anything, might be why it's lasted 3 years).

    Anthem X cracked frames.-crack.jpg

    Going in today to see about a warrenty replacement (going to be fun, as they haven't had any 26ers here for the last 2 years)

    I just found an identical crack in my 2011 AX29. I really, really liked the polished frame and I'm guessing I won't get that finish replaced. Sigh...

    This is what they were passing out as replacements as of May 1, (for a 2013 Anthem X 29 Size L that I broke):



    It's a 2012. Came to me with a new Fox RP23, but I had the CTD that came with my 2013 installed. I think it's actually better looking than the 2013 colorz. But that's just me.

    I'm in Colorado, USA. I assume you're in the states as well, given your John Deere motif.

    The frame I received is blue black and white. Its a 26er. I'm assuming its from 2010. Threaded bottom bracket and non tapered headtube. The suppiled shock is a Fox Float rp2.

    Thanks for the "heads up". I am about 4-5 hours away from Salida just over the border into Kansas. I get to Colorado Springs to ride with friends a few times a year and we are hoping to be in Salida for a weekend some time this summer. Small world with the internet, eh?

    I bought the frame from Colorado Cyclist and requested they ask Giant if the crack is of any real concern. That's how bad I want to keep the polished frame. I'm guessing they will want to replace the frame. I just can't see how a crack on that little bridge to the seat tube in the lower shock "cradle" will have any real effect on the bike's safety and longevity...but I know nothing.

    My other thought is, won't it just happen to a replacement. I have ridden the 2011 very little since I bought it...and I mean very little. I thought I was going to do some racing but never had the time.

    I have no idea how long it's been there. I just saw another post in this thread with a break in that spot and decided to check. I also checked the top tube/ seat tube spot but it is still good...I have an XL.

    Here is my 2012 x29er 2. Mine is just shy of a year old. No warning or indication of slight cracking before, just a clean snap. Shop had another model with the same problem although it was a 2010. Just hoping there was an improvement somewhere. I dont want a replacement that will knowingly break.

    They are going to want to replace it. They definitely don't want people out there riding damaged frames--their lawyers advise against that

    Mine broke after 4 months of riding. I ride lots, and there was a 24 solo in there, but I was amazed at how little time it took.

    I definitely am worried about it breaking again. I have almost as many miles on my replacement frame as I had on the oridinal, and now our high country is opened up so I'm riding more technical stuff... I check the top tube at the seat tube weld after almost every ride.

    If this one breaks, I am going to ask what it would cost to just throw the warranty replacement at an upgrade to the advanced. I have been leery of carbon fiber for mountain frames, but willing to take a chance that it would be stronger at least in terms of flex cycles. And of course lighter.

    The saddest thing for me is that I love the way this bike rides. For the endurance rides I do it is perfect. Light, efficient, comfortable, near perfect fit for me. But if another one breaks and I can't justify whatever it takes to upgrade to the CF frame, I'll be forced to cut my losses, sell the replacement and look for something else.

    Is this an issue with Carbon or Aluxx frames? Think the 2014 will address these issues?

    It's the Aluxx. I haven't heard about any non-crash failures of the advanced (carbon) ones.

    If there's a redesign involved in the 2014, it would be AMAZING if they failed to fix it. It would actually be sad--there was a recall in 2011 and they have kept producing the exact same design for two more model years? If they don't resolve it with a new design, they are either bad engineers or don't care. I don't believe either of those things are true, I'm guessing it was just a business decision to deal with the design issues for a couple years until it was time to re-visit it.

    Wow really? I've finally narrowed down my bike choice to the Anthem x 29er a few days ago. Kinda makes me want to wait for 2014's come out to see if they address the "issue"

    I'm going to question the idea that this is a straight up design problem or that a minor tweak wasn't made to fix it. Here's why: It's straight up illegal to sell something that's been recalled for safety issues. So there are a number of options here. Either the 2011 bikes that were recalled were produced with a bad batch of tubes, or they've changed something in the process that should solve the problem. Most of the cracks I saw in frames looked like they were right across the front side of the weld connecting the top tube to the seat post. Being right across the front edge of the weld indicates a possibility that someone got a setting wrong when they made that weld. It's just a thought.

    On a brighter note, I've had my 2013 Anthem X2 for almost 10 months. I ride frequently, and I ride it pretty hard, although my riding probably mostly falls well within the bounds of XC that the Anthem was designed for. I weigh just north of 200 lbs, and my frame is in good shape so far.

    Buy the 2013 if it's discounted. If you break it, you'll end up with the 2014 frame anyway.

    I'm adding another photo to the topic. My buddy's <strike>2010</strike> 2011 Anthem X frame in size M has just cracked today during a regular ride. He has ~12000km (~7500mi) in the frame.

    I think we'd need to know how many Anthem's were sold and how many are cracking. It's quite possible that these cracked frames are from a bad batch. Perhaps a bad session of welding or some other issue?

    There are 2 issues,

    1 bad design
    2 bad welds

    In some of the 2011's there were bad welds on top of the bad design , and so failure rate was very high. Subsequently it's just been bad design so riders who sit and run longish seat posts would put the most force on the area, and even then generally it takes some thousands of kms for the crack to develop.

    I do not believe its a safety issue, as the bike doesn't break in 2 - it's a triangle, so when one angle disconnects , the other 2 hold it together

    So far then pictures of the 2014 anthems seem to have redesigned this area in line with the trance

    I don't think so. The only frames I've seen that look like they are "redesigned" are the 27.5" anthem frames, I don't think the 29er has been changed.

    All I've seen are spy pics and unlabelled giant pics , but they are consistent for the junction on the 27.5, the xtc and the carbon. I'm extrapolating , but what we need is a confirmed 2014 colour way in Aluxx in a 29 er. All pictures point to a change, confirmation requires a specific from giant - a week or 2 perhaps?

    More to the point I haven't seen any pics of a 2014 colour way with the current design.

    I've seen the 2014 dealer catalog. The 29er frames haven't changed in those pictures. Hence my suspicion that you've been seeing 27.5 frames.

    Well obviously not enough people are cracking them then. Other possible, is their plan is to move over to carbon only for the anthem 29 er in 2015, and so couldn't be bothered to change their frame design.

    In the races I go to, almost every other giant anthem is a replacement frame - ie because I know the shock frame combos, I ask other riders where theirs cracked- it's always the same answer. It's obviously not a proper survey because it misses the 95% of owners who don't race, and probably do a 1000km or less a year.

    Or it could be that they aren't planning on continuing to make the 29er at all, pending how sales of the 27.5 anthem stack up. I guess we'll have to wait and see.

    Does this thread cover both 26 and 29er Anthem frames? Are both frames having similar issues?

    just got mine back yesterday. same exact frame so hopefully this one doesn't break! i had to buy a new bottom bracket for $60.00 and other than that no charge on the swap. the bike shop did use zip ties instead of c-clips so I may have to swap them back.

ID:	795583 whole frameset arrived with a brand new shock. They rear shock mount seems to be the same design as my 2011 frame; I hope that this one doesn’t break.
    Here are photos of the crack and my new ride.
    Is that the drive side shock mound where it's welded to the seat tube? Pretty certain my frame has just cracked right there. I wanted to make sure I was seeing what I think I am as far as what's cracked there.

    That's it? I've had my 13 Advanced 0 since September, put over 1600 miles on it and I weigh 200lbs. I don't see your point I guess.

    Sometimes things break. It doesn't seem like there is a single contributing factor to these broken frames.

    Yeah, there's certainly no point I can put my finger on where I feel like "oh, that's what did it" - in fact, I've had my bike less than a year, have somewhere around 900 miles on it, and oddly, two weeks ago sent it to the shop to have the suspension serviced. I've ridden it 3 times since then, and the mechanic who did the suspension service was riding with me when I found the break. So I'm going to say it's a pretty solid case, given the location of the break (right along the front edge of a weld) that there was a manufacturing issue with the frame.

    When you build so many of something, no matter how high your quality standards are, no matter what your inspection process is, it's possible for some variation - perhaps it was a drop in current from the electrical provider at the factory? - to cause a weld that LOOKS fine to have some problem. That's why Giant chooses to put lifetime warranties on their frames, and why they inspect this stuff for crash damage, abuse, etc. It would be very easy to try to abuse the warranty, but it's designed to allow for occasional manufacturing problems.

    Heat Treating?

    I broke my 2013 Aluxx X 1 after 1200-1400 relatively easy miles between January and April when I'm not able to get into the mountains to ride the really punishing stuff. They replaced it with a 2012, and I've got almost 2000 quite intense miles on that one now with no trouble (knock wood).

    One idea I had: heat treating. When aluminum frames are welded up, the places where the tubing got heated up have a different molecular structure than the places that didn't get hot. So after the frames have been stuck together and before they are painted, they are put into an oven and heated up to anneal the stresses from welding.

    They probably do this with a very large oven. What if the temperature near the door to the oven is lower temperature or not as consistent as in the center? What if your frame was hanging on a hook near the door rather than in the middle? What if for some reason during the time your frame was being heat treated, the oven didn't get quite hot enough, or the frame wasn't left in there for quite long enough?

    That said, I still contend that the design of the Anthem main triangle is flawed. Design is more than just a blueprint: it's a production plan. What weight of tubing, what method of welding, what heat and duration of heat treatment, etc. When the finished product gets pooped out at the end of the production process, if it has a relatively high failure rate, and a relatively consistent failure mode, something has been missed along the way.

    For my part, I'm really pleased that my replacement frame is holding up. The bike really suits my needs right now. It fits me well, it performs very well. I like it. I really hope that mine now is one of the ones that's going to last.

    More to the point I haven't seen any pics of a 2014 colour way with the current design.

    I'd go for it. I like last years specs and price points much better than the 14s.

    Wanted to report a very pleasant warranty experience with Giant. I had an '11 polished AX29 in XL that developed a crack in the lower shock cradle.

    At first Giant said my options were a '12 grey front triangle with my polished rear or an '11 polished front triangle. I was pretty happy that they still had some polished '11 fronts as I really like the polished frame.

    However, I was concerned that, at my size, the new frame would just do the same thing. I had ridden the bike very little over the past two years...less than 200 miles. I expressed this concern through my dealer.

    Giant came back with an offer to exchange my entire '11 aluminum frame with a '13 Advanced 0 (blue/black) entire frame minus shock (I keep my shock). The good part...the exchange only cost me $300. $300 to upgrade to a 2 year newer carbon frame? Yes, please.

    This seems almost too good to be true but I have the Advanced frame in hand and only $300 left my bank account. Good stuff!

    If you've tested one and like the bike, as Cotharyus said, go for it. The warranty is excellent, so although it's annoying that you're out the bike for a bit if it happens, you'll get a new frame back at that time.

    My own experience with a 2011 X1 26'er that just went through the process was pretty decent. It took 3 weeks, but at the end, I went from the alloy frame (with a number of scratches and rock dents) to a brand new SL0 full carbon frame (still a 26'er, think it's a 2012 model, last of the line), for zero cost. Not everyone is that lucky, but it can happen.
