    This is the right headset bearing?


    I have a problem with the upper bearing of the headset. The bottom fits perfect but the upper bearing is smaller than the cup, and this cup seems not having enough depth. The size of the upper bearing is standard IS42: 41.8mm 45 45 8mm height... But, look these pics

    Get a 7mm one or, replace the top cap with a dropped cap which will cover the gap or, ignore it.

    what frame is that? at first I was thinking it was an internal headset not an integrated one, but then looking at the pictures is actually looks like a it's a taper and they got the 2 cups molded backward on the frame ..?

    I deff would NOT ride it like that.. the bearing WILL shift around and wear the frame making it useless.. I'd get in contact with the seller(guessing it's a new frame from the looks)
    Going to try and bring Trail Tire TV back. go take a look...

    your upper bearing looks like a 41mm 45x45 campy style bearing. measure the id of the frame and od of the bearing

    Is that the IP-057/56 with FSA headset? I have the same issue, but with the lower bearing.
