I know this will seem like a cant be arsed googling thread but It's not. I bought my bike back in March and after 9 months of the tweed valleys finest conditions the BB is definately goosed. No Play in it but It's shagged. Had the bike into get some new brakes fitted and the mechanic confirmed. It's a boost Sram DUB and in the past I've ordered one for my sons commencal and got it wrong, in the end the same shop had problems getting a BB and used the original internal shell and new cups.
Anyhoo as said any help on links to order would be appreciated. I think If I had the money I'd just bite the bullet and go Shimano with new cranks as I've just bought 4 pot slx's as well.
Do not watch Hambini's video about DUB.
Trek's tech site lists it as a Sram DUB pressfit MTB 92 (zyro-fishers code is BBDUB6000, though they're out of stock until March).
Thanks folks , thats very helpful.
