I’ve had issues in the past with skeletal stems with dinky 4 mm hardware not have enough surface area or clamping force to keep a headset from coming loose. This one looks too skeletal to me. A stem is not where I like to save weight. This stem isn’t too skeletal on the steer tube clamp though. Probably not an issue for the majority. In my case the problem came from a fork change. I retired a Pike and replaced with a DVO Diamond. I think the stem was a Chromag 35 mm job. Lots of cut outs. Replaced with a cheap stem and the problem went away.
