I have just sold my Cervelo and it has a BBInfinite Campagnolo unit installed.

The new user will be using SRAM.

I need to get it removed ASAP. I am based in the UK. Getting the tool from BBInfinite will be time consuming and costly. I won't be using the unit again since my next frame has a good old fashioned threaded bb.

The BBInfinite method involves an airline, air hammer and their drift (none of which I have!)

So, a few questions:

1) Is there another way of removing it (bearing in mind I won't be using it again)? I have Google'd a search, but there doesn't seem to be any other way.

2) Does anybody in the UK have the tools by any chance?

3) If I can get the tools, is it really as easy as it look on the video?

Thanks!

It can be pressed out in the same manner as a threaded insert that is pressed into a BB30 bottom bracket shell. I used a spare peice of PVC plumbing pipe 4" long, 3" in diameter(I think) and used the plastic driver bushing supplied with the kit to reverse the process outlined in the installaton directions.

Tried that and the pipe just deforms. The BBInfinite does seems very well fixed in place.

Has anybody tried the official tools, and does the technique work as easily as they make it appear? If so, in order to remove the bb cleanly and without damaging the frame that I about to sell, I am not about to bodge it for the sake of a few £s and will probably order the tools and search for somebody who has an air hammer (not exactly a common tool in the UK!).

Just re-read your original post and would ask why not pursue the simplest approach and replace the bearings with SRAM GXP? The outer diameter for the bearings is the same for both bottom bracket styles and the bearings are easily removed with a bottom bracket tool kit or even with a Park Tool BBT-90.3.

If you don't care about the drive side bearing, the quickest way to remove the assembly is to use a brass punch placed against the drive side bearing face then use a dead blow hammer and to drive the assembly out by force. I used 2 sections of 2" PVC couplers and there based on the thickness, there is no way this would deform. That said, a pneumatic air hammer would be a common tool for a technician at an auto body repair shop - you do have those in the UK, right?
