    2013 Dakar XCT 650b Pro Frame cracked.

    I have a 2013 Dakar XCT pro that the weld cracked at the weld where the top tube and seat tube join. Jamis has been awesome and replaced it with a 2014 so I'm happy about that.

    The problem is I think it wil probably happen again. The thing is I'm between a L and XL and went with the L. My seat post pretty high, but the minimum insertion mark is inside the frame but barely.

    So does anyone know if this is a fluke or has it been an issue with others and whether the 2014 frame has been reinforce in this area. It looks like the exact same frame so I'm thinking no.

    Thanks for any help. I hope it's a fluke because I love the bike.

    By the way I weigh about 195 with gear.

    Already using the longest they make. There is plenty post in the seat tube I think.

    Thanks,

    If it cracks again go with the XL. The taller post height creates a larger moment/load on the frame when you rock back and forth in the seat than if you have a shorter moment arm/post height. I'm between M and L and prefer to ride L with the longer top tube and never had issue with cracking frame @ 220+ lbs. Current ride is carbon XCR Pro 29er.

    Actually Jamis wants to swap it out for an XL before it cracks again. Jamis customer service and warranty are by far the best I have ever seen and I've seen many.

    Not sure if Jamis is still saying they don't have a problem with that frame but I'm on my third frame already. Same frame as yours and same cracked weld as yours. It has to be something in manufacturing because I know someone else with the same exact bike and no problems what so ever so hopefully you'll get one of the good ones. You're right Jamis does have really good customer service though.

    I was wondering if others where having problems with this frame, but had a feeling they were. Hopefully this one will be a good one though.

    Good luck to you!

    I had a 2012 frame crack in the same location. I'm on a 2014 now, hopefully it holds together.

    I had a 2012 Comp that cracked in the same location seat tube/top tube, replaced with a 2012 pro frame, cracked that one at the chain stay, just got my bike back with the 2014 comp frame as my 3rd replacement. Jamis warranty service has been great (thanks Tim) even more so in the last case as I had wheel compatibility issues going from a 2012 to 2014 frame and they threw in a rear wheel as well saving me $$$$ from not having to buy a new wheel/wheelset.

    Dan,
    Is there a big difference between yours a d the other guys seat post? Is your higher than the other one? From what I've heard that's the issue with some of them like mine is right at the minimum insertion mark which puts more stress on it. I've been riding a L for 7 years and never had a problem until now.

    I'm riding a large frame also and the minimum insertion line is 2" down from the top edge of the seat clamp and the other riders bike is a medium and his seat post measures almost 3 down. I'm right on the m/l border line so I went with the large which I think fits me pretty good so going with XL for you might work out good. I should say the 3 frames I've had have all been L. Definitely think stress has something to do with it if you look at the way the frame bulges out to mount the rear shock just under the top tube it seems like there could be some flexing at the bottom of the seat post in the seat tube. With some luck an XL frame with a long seat post will work for you.

    Well the L comes with the longest seat post made so I can't go there. Hopefully the XL will work, but I have to agree with you on stress by looking at the seat tube where the shock connects, but you would think there is enough to avoid the stress. I know if you look at most new full suspension bikes they are reinforced at that well by either another tube running up and flaring the top tube so there is more of a weld.

    Time will tell.

    Picked my bike up with an XL frame, but haven't had a chance to ride it. I'll let everyone know how it holds up. Again Jamis warranty and customer service are awesome.

    Been riding the XL 2014 frame now without any issues at all. Pretty sure my issue was I just bought the wrong size so all is good now. I'll say it again that Jamis has the best warranty dept and customer service on the planet.

    Thank you Jamis,
