Really nice.

I definitely want one for my next build.

1. I can avoid the heavy 31.8 quill stem (and having to paint it).
2. I can go with a Chairman Mao stem and bars.
3. It won't look silly if it's about an inch above "slammed."

Kudos. Bravo Zulu.

Very nice. Now you have me scouring CL for an older bike that has a threaded steerer tube.

Thanks for the hand clapping

For now, it is best to contact me directly if interested. Amazon ordering will happen, just not there yet.

Thanks! I am constantly looking myself, mostly just hoping for a screaming deal on something even nicer than my 660, and sometimes paying attention for something that will fit my wife...Plenty to choose from if you aren't on a tight budget, and good groupsets, wheels, and cockpit bits are pretty cheap these days.

Amazing - thanks for sharing this. It's so interesting to see such smart innovation "as it happens in real time." I realize you must have been working on this for quite some time, but relative to the time line of commercial products, we're seeing this very early. I don't know what the market might be for this product, but it's not going to make anyone a millionaire, so it's also interesting to see a product being developed by someone who just wants it, and is willing to develop a high quality solution primarily out of passion for the idea. Very cool indeed.

Here is one in use, even after I messed up the installation. Outstanding bike component.

I'm using a 31.8 carbon bar and a 1 1/8" to 31.8 stem.


If I'd chosen a 25.4 or 26.0 bar, I would have found a more petite stem. However, this build was fairly anti-traditional other than the frame, so while I wanted a stem that didn't detract from the appearance of the bike (like a futuristic carbon), I still wanted to use my 31.8 carbon bar.

Note the outside diameter of the steerer spacer/stack is roughly = to the outside diameter of the head tub lugs.

Add another VERY pleased owner of one of these brilliant headsets. Well done, Joe!!!!!!!

I'll get some closeups soon, but at the risk of overposting the post-build photos, here's one that shows how the stem integrates with the bike:

Again....

I scored a Threadless fork for that Ironman redeaux , so I moved the Innivyclr to my Klein, with a carbon bar. Liked it so much I swapped in a carbon seat post and new saddle.

sorry if this offends you @joejack951, but do you have any production samples using a "regular" top cap for sale? I've got a few sweet top caps I'd love to use with my ironman and a 31.8 bar.

This creates a market search for more “petite”stems of more slender diameter. My kingdom for a 70mm Salsa or polished Nitto look-alike.

While I'd love to be able to tell you that you can use any top you wish with this headset, that's not the case. A threadless headset top cap has a much easier job than the top cap in the inni headset. The former merely has to withstand the headset bearing preload forces and only until the steerer clamp bolts on the stem have been tightened. It can be removed at that point if one so chose to.

The inni top cap is more like that on a standard threadless adapter: it has the support the wedge which is anchoring the quill into the steerer tube. This is a pretty critical job if you can imagine and the top cap has to be designed to support that load. The early prototype top caps I made were designed around an M8 socket head cap screw, much like you'd find on a threadless adapter. The new top cap design use an M8 stud integrated into a broached aluminum cap, which I think looks far cleaner and left more room for logos Nearly every threadless top cap is designed around an M6 socket head cap screw. The latter also use much thinner cross sections as they simply will never see the kind of loads that a threadless adapter or the inni top cap will see.

If you want to customize your headset, let's talk and perhaps we can get you what you want without compromising the design/safety.

I'd say it creates a business opportunity, one that I plan to address once I get this headset moving more! I'm willing to talk now to anyone who wants something sooner, just be warned that the price will reflect the prototype nature of the stem.

Good question, and I will be updating my spec list above with this info:

Steerer tube requirements:
1. Must be 27mm min/45mm max longer than bare headtube measured from fork crown
2. Threads on steerer tube must end no more than 16mm above the edge of the bare headtube (using fork crown as reference)

I need to take some pictures demonstrating how to take these measurements but hopefully they make some sense already. And regarding those measurements, most paired frame/forks will meet those specs. The only ones that won't are when numerous/thick spacers are used between the jam nut and upper race. When trying to combine some random frame and fork that have never previously been assembled, you will want to take some measurements first. Too short is a safety issue. Too long and you won't be able to preload the headset bearings.

In other words....

I used a fork for a 54cm and put it in a 56cm and it worked just fine. The adapter really helps compensate for stack height issues I've encountered for years.

Do you mean "not less than" instead of "no more than"?

Sorry if I'm not understanding this properly.

I am using a double negative which I should know by know by now is a confusing way a stating things

The intent of that measurement is to ensure that there are enough threads on the steerer tube so that the adapter can thread on as far as it needs to. Depending on the excess length of steerer tube present, that could be anywhere from 29mm of threads required (45 [max length steerer] - 16) or only 11mm (27 [min length steerer] - 16). Does that help?

A picture is worth a million of my words so I will work on that.

Balance

As an innicycle user, maybe I can help.

The streerer can stick up above the head tube just like it would on an normal headset install. There is enough room up inside the adapter to thread down over it. How much extra space there is in there, i do not know.

You cam also use a fork that’s a bit shorter, maybe one “frame” size. You just need to make sure you don’t run out of threads on the fork.

Putting it simply, the adapter is more forgiving of fork steerer length variances.

Reading through the thread, I didn’t see what might be yet another market for you. Weve seen a few damaged fork threads posted on BF, and some steerers cut just a bit short for most any standard quill type headset.

Am I correct in seeing that this could be a nifty “problem solver” fot those instances?

I've installed 3 now, so I'd say yes.

Over the weekend I was riding one of my old bikes with a nitto pearl stem that squeaks sometimes and found myself thinking about replacing it with one of these super-cool threadless conversion headsets. While modern threadless stems are functionally superior to a quill stem in just about every way, I still prefer the aesthetics of a quill stem on an old steel frame. I do have some modern steel frames with threadless headsets and stems that I've learned to live with so still considering.
