Sorry if my use of the word 'lockring' wasn't accurate but I couldn't = think of anything else to
call it - let me know what it's really called!
To describe what I see, there is a kind of threaded ring/cylinder on = each side of the bottom
bracket (ie part of frame housing pedal axle & = bearings). The pedal axle passes through each ring,
which also seem to = hold in the bearings (some of which fell out because of the breakage). = One
threaded ring has indeed sheared into two leaving an inner ring = about 0.8 mm depth screwed in the
bottom bracket. The missing outer edge = had notches that would have been used to unscrew.
There are no cups involved - it might help if I mention we are talking = about an old racing bike
(Raleigh Record), not an MTB.
Hope this helps.
Paul.
