Lurcher headset and bottom bracket sizes/options

What are they? Too many standards these days, will be for tapered forks, hollow tech cranks.

Yes the one one ones are the obvious answer but crap so fancied something else

Got standard Shimano press fit BB with XTR cranks & H/S is an FSA something & also running tapered forks. All have been fine.

Got a hope in mine and the OO standard token bb. So far so good bar a regreasing after a big ride in wet wales. BB is a doddle to change so bought a spare from SS for a tenner.
