Will it displace any houseless folks?
This is a serious question - there are a couple blocks in Portland that got a bad rap for placing bike staples to deter/abate on street camping
do it
next step kill the parking spot out front and add street racks

No. Itâll displace nothing and no one.
Extremely dumb q: I ordered a for-parts Tange G-Master roller bearing headset off ebay for $10 and was going to take a $13 chance on some replacement Stronglight bearings in there as theyâre both the same number of needle bearings (20) and why not.
But before I do I might as well ask if anyone has tried this before? I googled around if any of this is interchangeable and all I found was an old google forums thread where Jan Heine was shitting on Tokens.
IIRC they placed something like 10-20 bike staples across their entire property frontage ie far more bike parking than anyone would use especially with the bike theft in that area, but who can blame them for trying an innovative solution to keeping their immediate area clean and safe

I never had any issues with my token. And I am a fat guy. Maybe I donât brake as good and hard as Jan
I honestly canât fathom how his problem is possible on a properly adjusted headset

Yeah lol Jan in 2016 had not even considered disc brakes. Seems fine on my disc brake / token bike

I hate the unnecessary cost and complexity of getting a needle bearing headset. The real irritating thing is that Neco pumps out tens of thousands of low-cost 1" and 9/8" models exclusively for Chinese bike shares and Japanese mamachari bikes. Limited quantity occasionally show on eBay and Aliexpress but never under the right model name. They clear out for $10-$15 and last forever.
Not helpful now, but in the future maybe!

I did pick up an extremely spare XLC 1" threaded headset for about $10 last time I put in a euro order. Extremely SeemsFine and is silver. Thought itâd be good to have around just in case.
I wonder about this design and what kind of radial loads it can withstand. The arrangement doesnât look like any commonly available tapered roller bearing.
Not wondering enough to do the math, however.
Preload is a little sensitive but it seems to work fine. Iâve been using one since 2018 on my gravel rando. Only had it apart once to check and re-grease and didnât notice anything out of the ordinary. Rollers are staying in place under spirited braking at least.

Surely youâre not braking as hard as Mr. Heine though.
Iâm curious now. Iâll try to forget this, If I canât. Iâll probably stare at the equation for angle vs load on tapered bearings for a while.
Math with a bunch of letters usually serves as a dissuading factor.
this makes me wonder if thereâs any connection with the random YST caged/needle bearing headset I got around the corner from a hole in the wall bike shop

the number of needles in the bearing is irrelevant
the only thing that really matters is the angle of the bearing seat (all Iâve seen are 45°) and whether the bearing races physically fit in the cup (which might not work if theyâre too thin or if the cones are mismatched)
your replacement bearings should fit just fine, but you shouldnât need them at all as the âfor partsâ headset is complete and this shit just doesnât wear at all

Iâve never seen any bicycle roller bearings that were tapered
the needles are always regular cylinders, just set at an angle in most headsets (but some like the Dia-Tech or Woodman use them flat as thrust bearings in the lower cup)
Yes this results in dragging the rollers like a locked differential â and thatâs exactly why shimmy fiends like them, because that supplies damping to the steering
But they were originally invented for durability to combat whatâs now known as âFalse Brinellingâ where your headset indexes itself. At the time the needle bearings were ostensibly for the bigger surface area, but actually worked by allowing the outer races to be an independent moving part from the fixed cup â implicitly adding a plain bearing to each end of the headset to displace under vibration.
Cartridge bearings of any kind get you this same property incidentally and eliminated needles from the market.
