Odd Kahlkoff headset design , how to tighten it up ?

[jambonsambo]

Hi Folks ,

Kahlkoff insist on doing things their own way with headsets .

index=1

Has any body got any idea how to tighten up / adjust the one in the video ?

It does not have the usual top nut , star nut set up as seen on threadless headsets . It seems to be tightened by screwing the notched part of the assembly just above the frame against the stem but I can't budge it as there are no faces for a wrench to catch on . Is there a special tool ?

Thanks for any ideas ,

J

Is that a lever the other side (can be seen on the left hand side of vid)? If it is, you need to lever that off first then adjust. You may need locking or pump pliers. Alternatively cut it off and put something else on. I think it would be unusual just one retainer to hold the headset.
