Back again about this frame. Received it tonight, inspected it and all is well, but one thing. The bottom bracket is not what I was expecting. I had Workswellbikes install the "BBright to Shimano adaptor" (planning on Ultegra 6800 for the crankset). I was expecting an adaptor, meaning something that converted BBright to something that would accept a Shimano BB. What it looks like I got was a full bottom bracket that does convet BBright to shimano but it looks as if it is actually the bottom bracket?

My question(s) are as follows;

1). I have a full BB there right?

2). If I want to replace that to run some type of Shimano BB (BB72?) what do I need? Do I need a Wheels Manufacturing adaptor to take some form of the Ultegra BB? If so what part for what Ultegra BB?

You mean 066 not 065, right? All BB adapters are actually the BB mechanisms unless they are just spacers. No matter whose you bought, Praxis, wheels Manufacturing, etc. it would still be the same. The Shimano spindle fits in that mechanism and you are good to go. Also it balances the asymmetrical BBright shell on the drive side without the need for spacers. I don't understand what you want different.

Press fit BBs are just bearings and a protective sleeve. Adapters allow those bearings to fit into a shell they were not originally sized for. That's all.

Fourtwelves

Yes, it's a 066, changed the title, hopefully it updates.

Hmm, I completely misinterpreted what adaptor meant here.

Is there any type of shell/sleeve that would allow me to fit a standard Shimano Ultegra BB?

Or should I be looking at a Wheels Manufacturing part for this? Like this;

BBRight? Outboard ABEC-3 BB for 24mm (Shimano) Cranks - Black

There is nothing different available. They are all more or less the same with regard to the aspects you are questioning. The one you have is really excellent. All that is wrong with it is that it is a bit porky. Maybe 40 g heavier than the high-priced ones. IIWY I wouldn't touch it. It is exactly what you need.

I'm fairly certain that you can't convert BBRight to BSA (threaded). You can buy adapters that accept a Shimano crank, but not Shimano BB.

You have the right piece, install the crank and move on.

Edit: BBRight is 79mm wide, which is 11mm wider than a standard BSA bracket. It is impossible for a 68mm wide Shimano BB to fit.

rpenmanparker 

I guess you didn't see where I recommend having the BB adapter shipped separately and then installing it later. The empty BB shell makes running the internal cables much easier.

Fourtwelves

Totally saw that and was on the fence about it, read a few posts saying it wasn't that big of an issue and weighed it against the horrible creaking noises of pressing it in myself.

A few more questions.:

1). Creaking. I've read a lot about press fit bearings like this being creaky. Anyone riding his one on their 066?

2). Wouldn't the Wheels Manufacturing one be more stable, less prone to odd creaks under load due to connecting inside the frame?

3). Also isn't the Wheels Manufacturing one, which forms a sleeve around the crank spindle, goof. To protect any cables in there better. I haven't wrapped my head totally around how the cables are run in there but it seems the rear derailleur might benefit from that. The front derailleur routing I get.

rpenmanparker 

If properly installed, there is no creaking. IMO you can't do better than the one that is already installed. The kind that thread together in the middle of the shell are often praised for stability, but I wouldn't worry about it. Worst case you can try what you have. If it creaks, either Loctite it in or get another one and try again. But no reason to take it out now.

The one you have now has a sleeve that protects the spindle too.

Fourtwelves

There certianly is no inner sleeve on the BB or bearings.

Though looking at cable routing I see the race on the underside of the BB that will channel and protect the derailleur cabling from the crank spindle. Not worried about it anymore.

I'll stick with what is there and hope for the best with the bearings.

If, after build I have issues, I'll look at the Wheels Manufacturing one I linked with replaceable bearings.

Thanks for the help all. The last road bike I built up was with external cables (and it was steel with down tube shifters). I've been riding XC bikes or fixed for many years.

rpenmanparker 

I'm sure mine had had two half sleeves that nested in the center. Can't explain the difference. BTW the bearings not being replaceable is protection against creaking. The cartridges are fused into the sleeves so they won't rub.

See the photo of the BB adapter on this page with sleeve way down the page: workswell wcb-r-066 carbon road frames

Makes sense about the pressfit everything. Thought I have read this BB from Workswell isn't the smoothest thing ever.

Also. Definitely no sleeve between the bearings in this. Totally open. Hard to get a pic but this is mine;

rpenmanparker 

Okay, but as you say it is hard to see. Remember that the sleeve will be sized for a 46 mm opening but the bearings are much smaller. Could it just look wide open from the viewpoint of the 24 mm opening in the bearings when the sleeve is 46 mm or so.

Fourtwelves

I follow you. But definitely don't have that. I can shine a light in there and see the inner frame. I emailed them about it asking what's up. I'm not really that worried about it now that I see how the derailleur cables are routed.

rpenmanparker 

Well at least it should be lighter than the earlier version. Gotta like that.

And running the cables should be easier with more room in the BB shell.

Fourtwelves

Spending some time with Google and coffee this morning it seems many of the new/current press-fit BBs for BBright/Cervelo don't have that inner sleeve. Ceramic or not. Almost all have no removable bearings too. Just for the very point you mentioned earlier

I get the mechanics of this now and don't know how I misunderstood prior to ordering (I'm definitely a "gotta see it to understand it" person often). I'm glad I have some options if I want to replace this one at some point.

I'm going to build it up and ride it as is and see how it performs.

The other Google topic this AM was internal cabling without cable guides. Good times that. I do think the BB I have will help make that easier.

rpenmanparker 

Yeah, run the cables before installing the crank.

Maelochs

This is the path i chose, and I do not regret it.

I was going to opt for the White BB (146 grams) for my 066, but I was slow to order and when the bike arrived, the stock BB was a little heavy ... but I am not a racer, so ...

I have zero complaint so far. I know I can shave a few grams (for a few dollars) when/if I need to replace the unit, but for now, it runs fine and that is what I like.

Fourtwelves

So you are riding your WWB installed BB (BBright to Shimano?)? How long? How many miles on it? Any issues/creaks/oddities? Is it smooth? Anything I should know?

Maelochs

I haven't tracked mileage ( I have it all logged but haven't done the math) but so far no creaking and no issues ... I was Really worried about creaking as it would bug the heck out of me, but so far it is excellent. it does what it does so well I don't notice it, which is perfect.

I have Ultegra cranks in the Workswell-supplied BB and even though I could switch at any time, I see no need.

Maelochs

By the way, the BB adapter in my WW-066 is fully sleeved. I just had the opportunity to check when my cable guide failed. So ... I will have to ride other bikes while waiting for the replacement, but at least I know the BB will work once the new cable guide arrives.

1-2) Creaking has to with the bearing/frame interface, a plastic shell won't add enough rigidity to matter and is just one more thing to creak.

3) The cables don't really need protection. The tension on the cable will keep it well out of the way of the crank spindle. It's potentially useful for Di2 systems, where you stuff the extra wire in the frame.

When did you order your frame? I'm curious since WorksWell have been giving the run around and well lying to me about their shipping past few weeks.

Fourtwelves

I ordered the frameset on 02.12.17,after about a week of back and forth with questions, it was delivered yesterday 03.06.17.

I dealt always with "Iris".

zymphad

Ok, took a while with you too. I'm dealing with Summer. But your excuse is Chinese New Year, mine was ordered a week after Chinese New Year was over. So annoyed.

Do you like your frame?
