Look what I found in an old Trek
This Bullseye bottom bracket (never heard of by me) has needle mains and roller thrust bearings.
It's a really nice design and in excellent condition.
I was able to use a shorter Shimano cartrigde for a nicer 'Q factor'.
A search reveals other Bullseye BMX products but aparently these items were not used much in road bikes.
A design that bridged cups and axles to cartridges?

Very cool!!!
"Bullseye" started out as "Durham" (Roger Durham Engineer/Cyclist) Way back in the early 70s.
I'd hang on to that, you don't see them every day
Cheers,
Chris

I believe Stronglight had it's own version for road bikes that only had needle bearings. It was an older design than that Bullseye and now commands a high price when they come up for sale to collectors.

Super cool! Thanks for sharing that with us.
It looks like you can loosen those allen bolts and move that middle chunk on the spindle to fine tune your chain line. Fancy!

Wasn't Durham the inventor of the greatly elliptical chainring as well?

Durham also did cartridge-bearing hubs (in your choice of combinations of anodized flange and barrel colors) with user-replaceable bearing assemblies---all you needed was an Allen wrench to pull the axle and bearings---back when Phil Wood hubs still had to be sent back to the factory for service.

I have one of those Stronglights, Campy taper, 102mm Italian. About 2/3 the weight of the Chorus 102 I have.

I've seen those hubs , and they are a marvel of engineering for the time .
Very impressive, user serviceable , elegant.

I had thought that Durham was one of those Lockheed engineers who got laid off and started his own garage-based cottage industry since Bullseye was always located in Burbank. Turns out not to be the case.

I forgot to show the decal on the aluminum tube that spaces the bearings at the same time keeping debris out.
Also shown is some 1980s custom shimwork aparently crafted by the installer.
Thank you for all the information so far. Hat tip for link to the interview Unworthy1.

Great interview- sounds like they may be getting back into the business in a bigger way.

Bullseye made super cool stuff. 
In addition to the cool as heck red derailler pulleys, I had a set of their hubs on my special-race-only-heels back in the day: 28 hole Red white + blue Bullseye hubs, Mavic GEL 280 rims, DT 14/15/14 double butted spokes, red and blue alloy nipples,
no need for skewers (the hollow steel axles were threaded).... 1330 grams total.
