an interesting curiosity (cartridge BB content)

[cce]

Pulled this from my road bike earlier - an early shimano sealed cartridge BB, model UN10

Plastic cups both sides, and evidently predating the shimano spline system - it uses a FAG-type tool for removal

I've never seen one before, and search both here and google turns up almost nothing

1991
part of the Nexus range.

i didnt think nexus came about until 1995 or so

Still waiting to get a good stretch of time to get these edited and up, but a rough cut of the 1991 English catalogue Nexus.

BB-UN10 was also used in the rest of the low end Road range, 500/300EX..
It'll be 115mm in length as it was a road bottom bracket.

Those thumbies look look like late '70's 'space age'. Never seen any of that groupset in real life.

it *should* be 113 for the cranks it was fitted to

rest of the bike was 600 ultegra with 105 hubs, so i guess a little cost-cutting had taken place

Those thumbies do have a distinct look. Quite like them.

Looks like they have the same steel clamps as the Tourney Thumbies had.

brake levers look like the tourney ones too.

Check on the axle for a DH marking, usual place probably, the smooth bits just outside the cups.
I say 115 as they only list it as 115mm for any of them, be it single or double cranks or some fancy thing.

EDITed marking
