The problem is the British used odd sizes that are now obsolete, So sourcing bearings aint so easy. Same with neck bearings, most are little balls in a cup but the machined sizes are all odd. For the steering necks you can convert to a taper bearing and race and use common bearing house parts but you have to machine a spacer for the race. Several places sell these kits ready made but I used to make them for custom builds.
Not quite as easy with the wheels, I have not really tried sizing or sourcing alternatives and in the past just used later model/year wheels instead. But for a restoration or keeping it period correct its something that has to be addressed. The rear wheels is a big problem and I have several projects I need to address this with. The axle openings in the frames on the rigids are smaller and different OD axle, The bearings on the wheels also use the taper bearings. Be nice if someone figures out a source for them but my understanding is really hard to find.
The Triumphs for certain years ALSO used a optional sprung hub, which was a weird design, Big ass hub full of springs, heavy as hell, Allegedly, if you try to take it apart the springs can kill a person and requires a special tool. But the bearings that hub uses are such an odd size they are made of that rare material called UN-OB-TAIN-IUM.
Be helpful to find out some alternatives for the pre 53 wheels
