I have a set of the 22mm neken on my 16.
I'd like to sell them for $300 shipped .
I think they may need to be warrantied or serviced. The one chamber seem to spin 1/4 turn out. The Allen tightens it back into place.
I've had to tighten twice since I've owned up, the function of this is still working. Just going to an old school solid 22
Driving home from track now I'll get pics when there off the bike
