Not exactly C&V but adjacent: 1-1/8 threadless roller bearing headset

I know 1-1/8" threadless headsets aren't C&V in the strictest sense, but I also know that we have a good number of members here that love roller bearing headsets, specifically the A9 stronglight. I'm one of them, put an A9 on my '82 Miyata 1200.

Anyways, I figure this topic might be interesting for the forum. It's a 1-1/8" threadless headset with tapered roller bearings, made by SolidBikes in Sacramento, CA. Not the lightest headset, 5.5 ounces (nice 1-1/8" threadless external cup headsets are around 3 ounces), but it's cheap, only $35.00.

I'm also posting here about it because there's hardly any mention of this headset anywhere online, despite there being a good number of threads asking about headsets of this size/type.

I'm not sure where to push this conversation, if anywhere...just thought some members here might find the headset intriguing. I purchased one and it's on the way in the mail, I'll let you all know how it goes!

the roller bearing itself looks quite similar to what was used in the Stonglight Delta and A9 headsets. They used a conical washer to provide a hard surface for the bearings to run on. I'm still trying to understand whether the washers also move around a little to provide some self-alignment or not. The rest of the headset is made of aluminum, resulting in a very light headset.

a shot of the Delta headset...


...and the details of the Delta's lower bearing assembly....

They don't.

Or if they do, it's not by design, and only successful by chance.

The races are cones. To provide alignment there must be a pair of (sections of) spherical surfaces.

The first AheadSet equipped bikes came out sometime in the early 90s. If 25 years is the cutoff for C&V, they definitely qualify.

MTBs and then BMX, with road bikes several years after.

Then I'll charge ahead guilt-free!

Update: They arrived yesterday. Will be posting some pics and a quick writeup in a week probably, there's a fair amount to do first in order to get the bike running.

For those interested...

The headset works great! Like most roller bearing headsets it has a bit more drag. Beneficial for the bike it went on, I wanted the front end to be a bit less twitchy and for it to ride with no hands easily. A little finicky to setup; the compression ring has to be tightened down on the steerer tube before tightening down the top cap. If you tighten the top cap first and then the compression ring the headset will bind, it's too tight. The directions sent with the headset do say to do this, but for some reason I second-guessed them.

Heavier than most headsets, but if you're looking for a cheaper 1-1/8 threadless roller bearing headset I can't think of another option.
