old school junior frame bb question

(1/1)

stevied:
got myself an old db turbolite and ive never built a junior before and ive never encountered one of these mini bottom brackets before, so my question is will this fit my frame
http://www.chainreactioncycles.com/Models.aspx'modelID=22376
if so do i buy a 68-110 or 68-122.5 (and what does this mean??)

also am i right in assuming that this bb will work with these cranks?

58 delray:
looks ok steve but give chainreaction a call and ask them as the stock both parts  :daumenhoch:

stevied:
so whats this 68-110 business all about then, im assuming its some sort of measurement?

HEYWOOD BMX:
68 is the bb shell width.Most mini/junior frames are 68mm (English thread) and 113mm axle length.

stevied:
cheers guys, i'l give them a call today  :daumenhoch:
