What size BB for a 98 Sunn Xcircuit

[STONEMONKEY22]

New frame arrived today and was wondering what the BB size was?

Also is the UN54 anygood or am i best off looking for an old un72

UN54s are OK, no more, no less. Plastic-y insert on one side is a big minus, IMO.

Seem to run smooth enough, and not amazingly heavy - so perform OK, but if you're after either period correctness, or proper nice kit, look for older / better.
