    Just bought a '12 Kona Unit and having a hard time lining up the wheel...

    I feel as though i cannot get the wheel lined up straight. What is the center point you use to ensure it is aligned? The dropouts evenly spaced? Tire running evenly between the CS yoke? The tire running down the seat tube? I would imagine all of the above, except I cannot get them all lined up together. When i match it up in the dropouts, it looks like it is off to one side over the other.

    Can anyone help here?

    just line it up so the chain is taught and the outer knobs of the tires are equidistant from the inside of the chainstays.

    Take some pictures of the tire in the dropouts and pics of your chain tension and the dropouts.

    Does it have track ends? Are you using a bolt on hub? Or a quick release?

    If its a bolt on hub in track ends, Just loosen and move one side at a time effectively "walking" the wheel into perfect alignment with respect to chain tension. Thanks Sheldon "if it aint fixed its broken" Brown

    With a QR in track ends you are just gonna have to hold the thing straight and tighten the sucker down. Its a trial and error process.

    To check for straightness, I flip the bike over and work upside down. Make sure the wheel is centered in the CSs. Then flip it over and make sure its centered in the seat stays. Then you are good to go!

    If I am understanding you right here, my 2011 kona unit same thing the rear wheel
    is over to the left bit a bit more in between the chain stays I have checked everything
    carefully and every thing is adjusted properly , not sure but must be in frame design
    I have not had any problems been very happy with my unit.

    It might be that the wheel is not dished accurately. Remove the wheel and flip it around and see if the problem switches sides.

    If it's centre of the chainstay yoke, and not centre of the seat tube, then most likely the frame, including the sliders, are the problem.

    Having said that, if it's not out by a great margin, just ride it.

    I have some pictures I will post up shortly. When I center it in the CS it is not centered in the seat stays, and is slighly off in the drop outs. Is this offset part of the frame design or is this frame defective?

    I do not think it is the dish as it is centered in the cs and not the ss.

    Is the wheel true? Maybe you are looking over something obvious. I hope so, because I am buying a Unit soon and I hope I don't have any problems like this. Good thing Kona has the lifetime warranty

    Sometimes it appears the rear QR is seated completely in dropouts...but most of the time that is the culprit causing misalignment, assuming the sliders are even. One would assume that loosening the rear QR, and applying downward pressure would force the rear wheel to be in perfect alignment, that's not always the case. It's hard to get proper alignment in the rear droputs with the bike upside puttting the tire on, with any kind of chain tension. Try bringing the sliders forward, easing chain tension, then play with position of the rear QR to get the tire aligned properly, then adjust the chain tension.
    The only regrets in life, are the risks you didn't take.

    A slightly crooked rear triangle is entirely possible, enough bike tool companies make frame and dropout alignment gauges to check these things. I can't remember how off the top of my head, but there is a method to check the straightness of the frame using a string

    If that checks out then the chain stays could have just been designed a little asymmetrical for chainring clearance or something

    I lined it up in the drop outs, and when I did so, it lined up at the seatstays. It is very close to rubbing the left side of the yoke in the chainstay, however. Was this frame designed with an offset in the CS to account for using a triple chainring? If so, that could be it.

    I am also using a Maxxis Ardent 2.4 out back as well, so that may not help with the potential for rubbing.

    That is exactly the issue I am having, and it is more pronounced with Ardent 2.4's. I lined up the dropouts, which made it in line with the seat stay, but positioned to the left side of the chain stay. My thoughts are the offset if you want to add a triple, so it doesn't rub the chain in the granny.

    Photos. It is either the design or the rear triangle is misaligned.

    Here are a few pics. Sorry for the quality of them, rush job.

    The drop outs are evenly spaced, as well as, the Seat stay. The chainstay are off to the left, but I'm thinking that it is offset to account for a triple. It is just tight with the 2.4 Ardent.

    You will find that very little movement at the dropout will make a big movement at the stays. I set the dropouts the same then use the lock screws to fine tune it at the stays. One side of the dropout is always a little off from the other.It could be the aluminum inserts that are not exactly the same not the frame.

    Honestly, I don't bother checking my seat stays when I center my wheel. I want my wheel in line with the center of the frame (chain stays, seat tube, and down tube,) so that it tracks straight. If I find that my wheel is off by a lot at the seat stays, then I know I have a serious wheel or frame issue.

    As great as tensioners are, the dropouts will need fine tuning like stated above. If all else fails, your lbs should be able to check your frame for you.

    Here is a pic of mine with stock 2.1 tires not as pronounced as yours, even with the
    2.4 tires it should not be that much I would think, that does seem a bit to much uneven
    it seems you have checked all the obvious stuff maybe take it back to the dealer.
    Mine seems to line up fine with the rest of frame normally.

    Have you checked the dish on the rear wheel?

    I think there is something wrong with the rear triangle if things are not fitting well. You can check alignment pretty easy- read this article by the Sheldon. It is about 2/3rds the way down.

    I don't like the sound of that. I am preparing to buy a 2012 frame

    [QUOTE=RPG;8553269]I feel as though i cannot get the wheel lined up straight./QUOTE]

    (emphasis added)

    It may just be a feeling. It looks aligned to me. The photos of the '11 and '12 clearly show the yokes are purposely asymentricial. The yoke's attachment to the bb shell is asymetrical! Ignore the stays and align your wheel with the pivot points of the bike: the bb shell, seat tube, and down tube. For more accurate results, remove the tire before inspecting.

    I miss my EBB. It was idiot proof.

    take it to your local bike and ask them to check the dropout alignment for you. they should have a tool like this:

    Why can't you just dish the wheel? It's far easier than trying to bend the frame.

    ^ you can't dish the wheel to accommodate the problem he is having. if the tire is lined up with the chainstays but not the seat stays, the frame is mis-aligned due to a manufacturing defect or a structural failure. no amount of fiddling with spoke tension is going to help that.

    HoW does the wheel look in the seat stay? Is it just as centered?

    Oh yeah if that's the case. My bad, I usually have to redish my wheel every year or so.

    Loosen the QR and put some pressure on the rear wheel then close the rear QR.

    So the culprit was....

    the hub wasn't seated perfectly in the dropout. I loosened everything, pushed down on the seat, and re-tightened the wheel. The I tightened the push bolts sequentially, and then the drop out bolts.

    Straight as an arrow. Thanks for all of the useful tips and feedback. Hopefully someday I can repay the favors.

    When i put in a wheel, the best way is to turnover the bike, put the wheel in, and give the tire a good smack down.

    Using a string to check the rear triangle

    Tie off a piece of string at one drop out so that the knot is towards the front of the bike.

    Just bought a '12 Kona Unit and having a hard time lining up the wheel...-tie_on_dropout.jpg

    Loop the string around the head tube

    Just bought a '12 Kona Unit and having a hard time lining up the wheel...-loop_around_headtube.jpg

    Tie it off on the other drop out -- making sure that the knot is at the same location coming off the front of the drop out.

    Just bought a '12 Kona Unit and having a hard time lining up the wheel...-tie_on_other_do.jpg

    Measure the gap between the string and the seat tube

    Just bought a '12 Kona Unit and having a hard time lining up the wheel...-measure1.jpg

    Or I suppose you could measure from the center of the seat tube, too.

    Just bought a '12 Kona Unit and having a hard time lining up the wheel...-measure2.jpg

    Of course, make certain that you don't distort the string as you take your measurements. If the gap is larger on one side vs the other, the rear triangle is out in the direction of the larger measurement.
