This lockring works. Definitely recommended. Mine was installed on a Trek Supercaliber. Change my 60mm stock stem to a 75mm -15deg spare specialized stem I have.

What I needed when everywhere else was sold out.
Thanks!

The locking ring works but for me I wish it was half the thickness. It's the same size of the factory spacers.

I was very happy to find this option for the knock block headset. Im now running the stem I want too. Bontrager should have taken this opportunity to step up their stem game but with this I’m running a renthal stem without any issues, no play, no trouble thru switchbacks. Totally satisfied

Nice beat easy to dance too,
I give a95!!!
