Tange LN-3922 BB in BSA 73 - 113(,5) a thing?

[Spankyfart]

I run a Tange LN-3922 68 - 113 on a bike and I dig them, possibly the best bang for buck out there.
Cannot seem to find one in BSA 73 113 for the Trek 990 (EU)
What is a good replacement that's available, found this but it never heard of it.

Good old SJS https://www.sjscycles.co.uk/bottom-...s-english-square-taper-bottom-bracket-113-mm/

Or a second-hand high-quality Shimano one from Ebay. The good ones are obviously good and last. I'll probably not wear out a BB on any of my 'non-commuter' (weekend/ retro) bikes before I meet the mortal coil.
I actually bought a 2nd hand 73mm Shimano (UN52?) one cheap for my Saracen Elite E-stay commuter - I had no idea what length I needed so guesstimated and it turned out fine. Been on there two years or so so far with no problems.

Yeah saw that SJS one, it'll be €80 once it gets here I'm afraid.
Want to spend €25/30 as I need to mock up and see if it's a good fit to ride but won't buy a real cheap Shimano as I'll break it in a year.

I can see the 73mm shell LN-3922 listed with a supplier still, choice of lengths but I don’t know if they are in stock.

Thats about what I pay from a supplier!

Nice find, they carry the 113 which I assume I need. If anything else fails I'll just have to bite the bullet.

I think I saw the 73mm Tanges somewhere (inside the EU) but can't find them now.

 

[Spankyfart]

Yeah the only hits are from the UK which is uncanny.
Since I don't know what width I need as the specsheet only says BB UN50.

Maybe something on Velobase for the crankset?
