Any question answered...

Yeah like 28.9 or something, but why

Using a bearing with a 30mm ID without having the inner race being naked against the axle?

So another bollocks standard.

I don't know what that does? Doesn't it just mean it's running on another surface anyway?

Thanks for looking!

Yep I just had to shell out 30 quid for the bottom bracket for my Nephew's mtb and on top of that another £28 for the tool because of course it doesn't use the same tool as GXP or HT2

Only reason I even heard of it is I just had a quick look at Quarq powermeters and now you can't get the ones like mine, it's all DUB versions. Meh.

I think they started with the MTB groups first but yeah they're moving their whole range onto it.

I'm sure it will be nice in the long run. You know for sure you can fit the cranks to any frame without compatibility issues, you get the oversize stiffer axle and reduced weight like BB30 but now for BSA too without BSA30 BBs.

But right now when everyone has other standards and wants to stick with them, it's just annoying

Yeah, but isn't that the same when ever anyone brings in a new, what am I saying, it's literally spelled out in that xkcd thingie above. I thought T47? was going to be what everyone runs going forward?

There's a T47 DUB bottom bracket :)
Frame standards ≠ crank standards

I don't even know what T47 is just that everyone seems to be talking about it for new builds. I just buy the shit that goes in my bike until that bike dies and move on.

Its BB30/PF30 size but threaded

Technically there shouldn't be movement there anyway, but maybe they wanted some plastic between the metals like Shimano HT2 BBs, avoids galvanic corrosion with alu spindles.

a rather large trailer

Is there a build thread for this?

Soon... GF's gone on a mission to get some marine ply. Decided to go for the almost-cheap option first in case we want to cut slots into it or whatever, then get the better more spendy surface once it's finalised.

But right now when everyone has other standards and wants to stick with them, it's just annoying

Bloody Shimano eh, same thing year after year?

Gotcha. To get rid of pressfit squeaks.

For 38c tyres - what size inner tubes should I buy? My options are 28- 38c or 35-40c.

The larger ones.

You know for sure you can fit the cranks to any frame without compatibility issues

No you can't, it still won't go in stupid BB86/92 frames. DUB does nothing that 386Evo wasn't already doing perfectly well, it just ties you to bike-specific bearings rather than generic 30mm ID cartridges, so they can charge three times the proper price every time you replace them

Edit: Stupid question

DUB does nothing that 386Evo wasn't already doing perfectly well

This is what I don't get, particularly when SRAM was already making 386EVO compatible cranks. Do you know what marketing bullshit SRAM came up with to justify not simply adopting 386EVO?

Still, another reason for the No More SRAM rule a.k.a. The Bauke Mollema principle. Not that another was really necessary.

DUB had to work on older and less progressive* threaded frames too, and squishing a 30mm axle in those is a bit of a ballache. So they dropped 1.1mm to make it easier :)

* Santa Cruz love a BSA threaded BB.

386Evo goes in 1.37"×68mm threaded shells, it's just like a big bore HT2/GXP/UT. There's plenty of room in the shell for a 30mm axle if you have outboard bearings.

Yeah I know but they run all sorts of other shit through their BBs don't they like dropper post hoses and brake hoses / cables.

Do you think a change in spindle radius of 0.5mm will really make any difference to that?

This!
