Innicycle threaded to threadless converter

Tired of your flexy old bars, but don't want to use an awful boat anchor quill adapter or swap your fork for a rare 1" threadless one? Years ago, I daydreamed of a solution incorporating the upper half of the headset, but joejack951 went and made one. Then he made more, and you can have one yourself. It's glorious. Comes in silver or black.

Yeah nah, that's been beaten up with the fugly stick.

9/8 threadless steerer extension gives you your choice of stems, and the Innicycle one is way nicer than the alternatives, even before you throw in ditching headset wrench flats and locknut.

Great product. I've built three bikes using this amazing headset. And the quality is VERY high, like up there with Chris King...

It doesn't appear to be any lighter than a quill adapter and headset., and a lot more expensive.

I like that Innicycle design that would be an excellent option and wish I had known about it long ago.

Maybe, but it's way sleeker, has less stack height, and provides a stiffer interface to make use of the 31.8 bars you can hang off a modern stem.

This is all I use for putting modern stems on older threaded fork bikes. Simple, high quality, doesn't make me change out a vintage headset for something that isn't native to the group I'm using and is height adjustable in 10 seconds with a 6mm Allen. I wish him well, but it isn't for me.

An uncut innicycle is 240 grams (90mm steerer extension). Cut down to 45mm (for a slammed stem) and with the steel stud trimmed, total weight is down to 185 grams.

Well, there you go. Quick googling says a campy headset is about 135 grams and the VO threadless adapter is 272 grams on its own. 407 grams for that setup vs 240 for an Innicycle. I haven't bought one of these yet but if I end up with a bike with a threaded stem that ends up being a long term keeper then I am going to seriously look at these.

It's possible to go even lighter with the headset.

https://velobase.com/ViewComponent.a...ee49c&Enum=111

but the difference isn't enough to justify the added weight of any adapter I have found.

and sticking to threaded stems if you want a stiff front end you have to pick a pretty solid stem which comes with a weight penalty - Seems to me the differences in weight are negligible and the inni upgrade is hard to argue.

Or am I missing something?

Perhaps even lighter exists but this is the ultra-lightweight headset that came on my Trek 660:



Not without compromise, those are plastic cups! It seemed to work ok for the few times I rode the bike with it installed.
