Thanks for the explanation. Sounds vaguely similar to one made by Bushnell ( not sure ) Seem to recall someone remarking how creaky that one was. Glad yours is working well. Thanks again
No, very different to a Bushnell, my experience of that was indeed creaky and it's a common complaint, along with them having a tendency to seize if not serviced.
The newer Thorn type is a clamp design, think how the seatpost clamps in the frame and you have the basic idea. It's pretty much a bombproof design. Probably more importantly, it's foolproof.
That was the problem with the set screw type, issues were usually caused by unnecessarily small adjustment leading to indents not being sufficiently spaced to avoid slipping. I made this mistake on my first, and needed a replacement, once I'd worked out how to use it there's no reason for it not to last a lifetime.
