old school junior frame bb question
« on: December 15, 2010, 10:54 PM »
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?

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