I am working on a vintage English Viscount road bike.
Never seen this type of bottom bracket.
Can't take any cups of, at least don't know how.
Looks like a sealed bottom bracket with the bearings running in a groove.
There is a spring sitting around the spindle near where a cup should be.
Instead there is a rubber "ring", that can be removed and you can see the bearings.
Would keep the bottom bracket but it is a tiny bit shaky/loose....
Can this be tightened, if so how?
Anyone seen this and worked on it?
Any help would be great.
Also can this be removed and replaced with a standard bottom bracket?
Seems like there are cups pressed into the bottom bracket shell from both sides. I guess there are no threads in the bottom bracket???? Question, questions...
