Good news on the BB front, I found this (new?) SRAM DUB option online. It seems like a new option, because I have been looking for this exact BB and was unable to find it the last couple of months. Just in time, because my frameset arrived yesterday.

https://r2-bike.com/SRAM-Bottom-Bracket ... T47a-77-mm
Is this information correct ?
From the r2-bike page: BB-DUB-T47-A1
And the sram page for this article shows a t47 (not t47a) : https://www.sram.com/en/service/models/bb-dub-t47-a1

The photos clearly show one internal cup and one external cup, which is what T47a is.

I have mailed r2-bike, just to make sure.
Since I also can't find the t47a on the sram site.

But you are correct, the pictures show a t47a version.

This is what I received, it is the T47-77-A. The type number on their site doesn't seem to match yet, but they did send me the correct BB.

The MPN is correct though: 00.6418.033.003

I'm a big fan of the BBInfinite T47a/T47i design. The NDS cup is a fixed length and creates the necessary offset regardless of shell width.

Received the same :)
Placed the order after you posted your picture.

Also received a reply from r2-bike (after my order was already shipped) :
With SRAM I assume that it is only a picture and does not show the original. We have the bottom bracket photographed directly with us and therefore both look different but it is both the same bottom bracket

I finally finished my Factor LS (Chrome colorway) build. It has a Rival 1 groupset with Force AXS 170mm crankset and Garbaruk 42 tooth chainring. I used an S-Works SL7 stem which aligns more or less perfectly with the low stack bearing cap. Other than that it has a Berk Lupina saddle, Deda Superleggero seatpost, 40cm Deda Gravel 100 handlebars and Arundel Mandible cages.

With these aluminium wheels it ended up around 8.3 kg as pictured.

I was quite happily surprised that these newer T47 frames do not have any fender mounts.

Looks great! It seems like you have 180mm rotors in the front (because of the 5 spokes), is that correct?

What headset bearings are you guys using? I have my LS only from september and only used it on road. Headset bearings seem to have died already..... there's no rust or play, just a small groove somewhere and if you corner, you feel that the bike wants to go into the groove. Haven't hit a pothole. If these are ceramicspeed headset bearings, they have a questionably durability.....
So, I'm looking for replacement bearings other than ceramicspeed. I can find same size bearings, but heard that most of them give a +2mm gap at the crown.
So, looking for recommendations. Thanks

I believe the bearings I got with it were just standard FSA bearings. But I can't speak of any longivity issues, because I have not ridden it a lot yet.

I thought all new Factor bikes came with CeramicSpeed SLT headset bearings. My first gen LS came with regular CeramicSpeed bearings but a friends newer LS came with the CS SLT ones.

- Factor LS Disc
- Specialized Aethos Disc
- Sturdy Ti Allroad Disc
- Guru Praemio R Disc

I have the latest LS, with T47a bottom bracket, should be the CS SLT ones then.... I ordered some enduro bearings with the same specs. Will see if they fit and last longer....

Received my frameset end 2022 with normal headset bearings, no cs slt.
If you really have the slt bearings you should have lifetime warranty ?
