I found this at the bike coop a while ago.

Octalink (Type One)

Flat needle bearings + round thrust bearings.

Pretty light.

Sorry, post accidentally was submitted early. Photos in a few minutes.

Ahh, found it as I was cleaning and getting ready to re-lube. Shimano Dura Ace 7700 Octalink

Unlike other Shimano BB's, this one appears to be able to be cleaned and lubed, as long as the bearings don't wear (parallel needle bearings can't be adjusted). I seem to have gotten it without the sleeve.

Bikes: '96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '20 Surly Midnight Special, All are 3x10. It is hilly around here!

Yeah, you have the Dura Ace Octalink bb which was indeed serviceable. The Ultegra and 105 versions were totally sealed and non-serviceable. A lot of riders bought the Dura Ace one for its light weight and were then surprised to find it was not set-and-forget.

A friend a bike shop said that it required maintenance often which probably killed it. If you maintain it, it will last forever.

An example of Shimano engineering at its best, and worst. The sort of high end component that makes people think that high end components are not durable, except they are if maintained as they should be. At that time, many high end bikes with Dura Ace groups were specced with Ultegra bottom brackets so that their owners would not have to deal with regular overhauls of the bottom bracket. Frankly, I would love to get my hands on one of these
