    Is my chainline really bad ?

    I dont know why. But there is no way to get a better chainline.
    The crank is already close to the chainstay. And my actual bottom bracket is 111mm Iso
    I just swapped the crank from the FSA Gimondi to the MICHE Primato Advanced
    Same problem...
    But when riding. I just hear nothing. A very very little noise. Like the chain is stretching.i do hear it only when going in silent places. Its not too big otherwise it will drive me crazy. Im just worried if it will ruin my chainring or sprocket..
    I do keep my chain really well tensioned by the help pf my surly tensioner. About 1/2 inch slack

    chain is not centered with the chainring and is doesnt sit in the center of the chainring. Is that a problem relative to bad chainlines? By the way i run a long chain, it is helpful to a bad chainline
    I will post the photo..
    Let me know what u think. Any is riding with a chainline like mine??
    It is too bad ??

    You should be all good. Track cranks matched with the correct bb spindle length on a track frame with a rear track hub will ALWAYS be fine.

    Except that Miche crankset should be used with a 107mm ISO spindle, not 111mm.

    And with the Gimondi he should have been running a 103. Youch.

    Edit: Hard to tell from the "hanging pic" but ten bucks says that chain is too tight as well.

    Ah, there you go! I don't know miche cranks and figured he matched it correctly. Thanks for the input! There you have it my friend. Get a different BB for ultimate smoothness.

    i think a 107mm Iso BB will not fit as chainring bolts will hit the frame. The actual BB 111mm to the frame.
    And it look like that.

    It was way too short. And left cranks were to close to hit the frame . Too bad

    I think a 109.5mm BB will be the best BB i could fit in there, but i dont find one selling this length.
    but the difference is only 1.5mm from my actual BB that fitted great. The 111mm iSO
    Best of luck to you.

    Yes. It is. The cranks are clearly labelled as JIS

    but any ISO will work as well.

    I've never in my life seen a Miche crankset that wasn't ISO (and I've seen a lot of them).

    Pic below:
    None of this makes any sense. The BB you use depends on the crankset you use, not the frame. Ever.

    Also, Miche Primato BBs are adjustable from side to side to overcome chainline/clearance issues.

    Both ISO and JIS are square taper. So both will work
    In the photo here i show a JIS 107mm on the left.
    and a ISO 110mm on thr right

    I have fit the miche BB 107 JIS
    But chainline still bad. And the 107mm JIS is not long enough for the non-drive side. So left crank will hit the frame

    When I was changing my crankset awhile back and considering whether to cheap-out by keeping my old bottom bracket, I searched all over this place before deciding to get the correct ISO BB to go with my cranks. But something that stuck with me from discussions I found on the subject was that in at least one instance, someone pretty well thought of around here supported interchangeability of ISO/JIS:

    As expected, you obviously know much more than Sheldon Brown on the matter of ISO/JIS interchangeability.

    from your "Pictures" it doesnt look like you have any slack in that chain at all, it looks tight which can also cause noise.

    loosen it up a bit, quit worrying about noises so much. my chainline is off by 2 to 3mm and no problems.

    this is my chain slack, some may say its too loose or maybe not enough ?? but i have zero problems. no binding ect. **** before i ran a biopace chainring which is of an oval design so when i adjusted for chain slack i had to adjust from the tightest point "without binding" because at another point on a biopace is very loose by design but not intended for a singlespeed but for a bike with a chain tensioner

    There is so much multi-level fail in this thread.

    Best of luck to the OP - with his bike and life in general.
