BB 30 Adaptor

bike boy

Does anyone know about BB 30 adaptors for Shimano BB?
Has anyone carried out this conversion?

Hope this helps.

Thanks Eamonnator
Is this pressed together within the frame, finishing flush with the frame?
It looks simple enough to install.

I de-BB30'd my frame using one of these - essentially the same as the SRAM unit. I installed it myself using a bearing press. It's not hard if you have some mechanical sympathy and the right tool. It just needs some anti-seize and to be put in absolutely square.

I experimented with a KCNC adapter before opting to semi-permanently de-BB30 the frame, but I was never satisfied with the adapter, it felt like a bodge job really. There are other, less drastic, options than the sleeve if you think you may end up buying a BB30 crankset down the line.

Yes it pressed into the frame. It is fairly easy to install.But as niceonetom says, you have to be careful, that it is absolutely square or you are liable to damage the BB bearings. It can be a bit of a bitch to remove.
The KCNC one mentioned is easier to install and remove as it screws into itself from either side of the BB shell, and no bearing press is required. You will however need two BB tools.
Here's a link to the KCNC adaptor.

Thanks again Guys for the info!!

@niceonetom So which one did you continue to use? The FSA BB30 sleeve?

I understand the KCNC adapter process, as you tighten it it wedges into the frame/ BB space.
The FSA BB30 sleeve....does this just slide/ pushed into the frame and the shimano cups screw into it? Does this keep the the sleeve form any movement?

I know it's not that complicated but just want to choose the right product!
Saying that the cheapest effective one as I have spent 1000 euro on the frame!!

I was going with this by gut instinct http://www.chainreactioncycles.com/Models.aspx?ModelID=44067

But is this the better option

I have a ceramic BB30 to Shimano adapter for sale if anybody needs one. Very little use.

Not too sure about using a second hand BB adaptor!!

Of the two you mention, I would go for the Sram.
If I were you, I would look into Briando's offer more closely and not dismiss it out of hand.

Having lived with the KCNC adapter for a couple of months I went for the sleeve. The KCNC unit never felt entirely secure to me - it slid into the frame just a little too easily and I had persistent creak problems. It also required plastic shims for my shimano cranks (I think it might work without these for KCNC's own cranks) so the was layers of adapting going on. The shims were also made from an EXTREMELY brittle plastic which broke the first time I installed the cranks (good thing it came with spare, though this does seem like an admission that the shims are too fragile for purpose) and then when I had to remove the cranks the shims took the bearings out of the adapters with them. Messy.

The sleeve is a much snugger fit in the frame, it's obviously machined to very tight tolerances - I doubt it'll ever come out but apparently it's possible, presuming the anti-seize compound has done its job. Once installed the frame functions exactly as a standard BSA frame would. Install any BSA BB you like and it'll work just fine. I doubt there's any real difference between the FSA and SRAM versions.

@niceonetom Nice one Tom.....I think I will go with the sleeve!

@Eamonnator Thanks for your advice none the less!
