Campagnolo 2007 - yes, Hollow BB
Translated from French
After the firsts Shimano 2007 news, some rumours about Campagnolo are spreading on the internet.
It is said that Campagnolo cranksets will be totally redesigned for the next year. They'll use a system similar to Shimano because of the external bearings but they will be ultra-narrow to lower the Q-Factor.
The crank/bottom bracket is different than the Shimano in that the crank is 2 “L” shaped items that fit together mechnically in the center of the bottom bracket spindle.
Still according to rumours, Campagnolo would be working closely with FRM and the first bikes equipped with the new cranksets would already be under tests on the road.
Negmass cranksets are using something that may look like what Campagnolo will be using next year:

Looks like the pipe is keyed together in the middle. If the bearings and bearing cups are secured to the cranks, threading the bearing cups into the BB housing could be all the side-to-side retention the thing needs. But then, to remove a crank, you'd have to unscrew the bearing cups.

What a shame to say goodbye to the wonderful Record bottom brackets! Ah well, I assume they know what they're doing.

Don't like it. Don't like small Q-factors, and I especially don't like that joint in the middle of a part that gets super stressed.

Well the word over at Campy only is that there are actually 3-4 designs on the drawing baord.

So is Campy tacitly acknowledging that external bearing bb's are a superior deisgn or just yielding to market pressure?

Great, yet another standard on top of ISIS, Square Taper, Octalink, HTII etc. Well I guess its all in the name of progress, but I'm not buying any more sodding BB tools, uh-uh.
That joint looks like a bad idea, as does the idea of ulta narrow bearings doesn't seem like a good idea for longevity. Is this all in the name of differentiating themselves from Shimano? I'd kinda wished that they'd gone down the HTII route so that things could be standardised, but that was never going to happen I guess.
Incidentally, what kind or BB does the SRAM chainset use?

I'll go out on a limb and guess that the 07 Record set will be lighter, stronger and more reliable than the current set, unless Campy decides to contradict the 74 year old philosophy of the company.

I still dont understand what the problem is with square taper. I've never had a single failure, misalignment, or any other issue with aplain old square taper crank/BB.

hello
ALL my bike are equipped with square taper BB's. I'll continue to use and replace them unless my next crankset of choice 'forces' me to use splined or other types of BB.....I don't have a problem with that also....

Seriously, bicycles have not had any real changes in the last decade or two, therefore, in order to market effectively, it doesn't have to be better, just different.
Compact cranks are a good example of this.
Campy is going to this setup for weight. Record is still the lightest groupset, but the heavy aspect has been the cranks. Record in 07 will be lighter.

People who look at this picture and say... "oh it's not a good design" don't have any idea what they are talking about. The basic idea is to create less pieces in the crank area. Two pieces is better than three. Less can go wrong.
Campagnolo is a very conservative company by nature. They have stuck with the square taper bottom bracket for a reason. Some say it is outdated and bla bla bla... but ask world champion Tom Boonen what he thinks about his winning sprint last fall. It works and works well. Campy has sent the last couple of years working on this design. I am confident that this new design will not make it to market unless it is strong, light, spins well and last a long time.

That was an isolated incident. There were many successes in the 2005 campaign with the new Dura Ace design. Please understand that I am not trying to flame. Just illustrating that things _can_ go wrong.
I'm sure Campagnolo will get it right. Being conservative has its advantages. They'll take the time to get it right before going to production with the design.
Still...
*sets out to horde every last Campy square taper BB and crankset he can find*
*hugs his current square taper Centaur BB*

a solution to a problem that doesn't exist.
I agree on the weight aspect of it but other than that
square taper just plain works
the good thing is that those square taper BBs and cranks the gcasillo is going to
start hoarding are gonna get dumped by the boatload by all the racerboy wannabes.
Ebay ought to be chockablock about a month or two after the final design is released.
