Collar.
Not quite so much to say on the cam-twist/Ti-stix, other than to say like the H20 cage, it redefined a genre.
The driver for the work, like any good design, was driven by 'need'. Need, at the frustration of essentially road based QRs with internal cams, breakingthier cirlips and falling apart on the trail. The cam twist design went through several iterations, before it for to the 3 hole design we know. Initially, the designs were basically wiing nuts, before they moved in to the hinged design
Here is the first set of machined 3 hole designs. Initially, as much for cost, they used threaded 3/16" stud, befor moving on to 5mm stud. Early ones were threaded all the way down, with the latter models using especially rolled stainless or ti.
Here is what soem of the cam twist levers look like midway through being set free of their billet:
Here is a rare set, produced for the japanese market in its triple box set guise. The Japanese distributors like to market stuff as "theirs", rather than just looking lik ethey sell stuff for other people and put a markup on it. Must be a cultural thing.
Later, because of the bulbous base of suspension fork legs, the "Twister" evolved. If you didn't get enough purchase, just flip the lever and wind it up some more. Again, this is some of the first batch of hand-machined prototypes.
As with many of the products, there were experimental pieces, and rare pieces. The dark blue here never made it to mass market, as the turquoise was stealing the show. And there are a couple of lavender and plum coloured parts that were tried out. Again, cool, but stillborn

The collars went through a few iterations too. The 3 hole design, slots, slotted section, with holes. Here is a selection.
Some of the first 34.9's used a recessed bolt, and looked like this:
I have several of these if anyone is interested.
