Will do!

For this production run, I kept everything generally the same as before but I couldn't let a few things go unchanged, having had a lot of time to think about the design.

1. As mentioned earlier in this thread, I have added the M5 threads to the threaded shaft allowing use of standard threadless top caps. As with a typical threadless installation, the steerer tube/quill will need to be cut a few millimeters short of the top of the stem or a spacer will need to be installed above the stem to allow the threadless top cap to fit properly (most protrude a few millimeters on the underside). In this configuration, you could then use the top cap screw to compress the spacers (or bell zenolee ) so that they don't rattle, assuming you are using non-innicycle spacers. Probably not something most will care about but it was a simple change so why not.

2. Weight weenie'ism is an infection I'll never cure and while I was initially concerned about using aluminum for the cone/wedge, I have decided that there's little to no risk in doing so. It saves >10 grams which, combined with a steerer tube and threaded shaft trim, bring the total system weight down an even more respectable level and within a couple grams of my abandoned ultimate-weenie design that was going to have a lot of compromises. A titanium shaft could cut another a few grams and ceramic bearings would chop a few more but we're getting into overly expensive territory quickly when things start going in that direction. I think I'm happy with where it currently stands with this one modification.

That's it for changes. Expect another update from me in about 5-6 weeks. Of course, I'm happy to answer questions in the meantime and do have a few silver headsets available still. This next run has been heavily biased toward the black unit which seems to be the prevailing color preference (both of my innicycle builds have used black headsets). I'm also continuing to toy with stem ideas though my focus has recently been diverted back to my thru axle fork project with the completion of a new kit for some popular Trek bikes:
