Hi,
I'm trying to find a replacement to my existing headset with no success.
I own a Cinelli Soft Machine MTB hardtale frame. The headset is integrated.
The diameter of the bearing is about 46.5 mm
Stear tube is 1-1/8" (28.6 mm)
Can you please advise what type of headset i need

    have you looked on the headset standards pades or on Parktools yet?
    does it have cups? or just pressed in races?

    I guess the top meassured part is a press fit into the frame or is it a slip fit? (tools or no tools to fit?).

    It doesn't have any cups, just pressed in races and it's a slip fit.

    yep so have you compared the measurement to the standards? as per above?

    Yes, I have compared the measurement to the standards, at least to the common ones. I even wrote to several headset manufacturers, but no one has anything compatible.

    I belive it's a proprietary standard.

    IS47?

    is the upper exactly the same?

    Yes, this is the bearing. if you'll look at the first picture in my first post, on the right is the assembled bearing and in the middle is the second bearing (disassembled)

    Both are the same size

    pic is a bit small haveing been reduced.

    ok so on the left we have.

    something at the top?
    top bearing cover and centering collar.
    and?
    center Top down
    outer race. bearing. inner race, seal.
    where is the part that sits on the fork? still on the fork?
    and the actual measured part is the top center part?

    You are absolutely right.
    The bottom part on the left is the crown race.

    The measured part is the top center part (outer race) and fits directly into the frame.

    P.S. Thanks for your time and effort

    I do have the same frame.
    And yes I do remember the same trouble when thinking about replacing the headset.
    No surprise that such style of headtube lasted only one year, too odd.

    Will bring it in the workshop one day soon and will double-check, a.t.m. can't remember exactly diameter and angle of the bearings, but they are needle ones, very similar to what used by Stronglight
    Ciao!
