weight 10% (ca 200 gramms) lower than the current one.

the weight savings of 200 gramms stands for the whole new group (not only for the parts in the picture) compared to the curent one.

...about 50g on my new groupo :)
ok, ok here's a hintFORT-Cyclist

this is not mine,
this is rear derallieur, sprockets and wheelset of the new DURA ACE group coming in 2004!!

...I thought the forging looked too good for Campy:)

.....looks like the derailleur is rapid rise. Am I correct?

It does look that way.
tell me more, tell me more...did you see very muchgmikes

Well apologies to the cast of Grease!

So what else can you tell us or show us of the 2004 dace? Is 10sp definitive? Are the shifters that much different from current ones? Can you fit current 9sp levers with new internals for 10sp as some have suggested?

I hear that the crankset will be the same development as 2003 xtr. I can't help but think that this will increase the 'q' factor of the pedals. Any comment?

Now the big question:

Will 10 sp work on current 9sp hubs? I hope we do not have to trash our current rear wheels to take advantage of the 10sp.

Thanks for all the info

radial on the drive side/non-radial outside?

with this spoking the drive moment and drive forces are going via the big hub to the left side. because radial spokes cannot take moments (until they get a little tangential direction by braking or acclerating).
the spokes on left side have less tension than spokes on the right side, so they can take the additional loads from drive forces much easier.
this principle origins from danish Kildemoes.

I'm just wondering how much that axle will twist under all that torque? 95% of all semi-radial wheels spoke the opposite way (just like the front wheels on a Ford Model A did....)

do you mean the body of the hub?
i don't think that this is a problem, the hub body has a diamater similar to it's lenght.
it is quite bulky.
