future of dura-ace(10 posts)

future of dura-aceesbike

Anyone out there have the inside scoop on the future of dura-ace? My ultegra components have some more life in them, but I would like to upgrade eventually. I would prefer not to do this right before they make some dramatic change, like going to 10-speed or adding carbon to their components. What is 2003, 2004 going to look like?

No changes as far as I'm aware for 03. Rumors have it that for 04 there are some changes planned.

... Shimano is probably waiting to allow Campy to continue to lead with certain innovations... before copying them and surpassing Campy (at least on a cost per performance basis).

... we've yet to see widespread use of carbon fiber in the Dura Ace gruppo... '04 seems likely (looks like XTR is getting the lion's share of early press releases)... along with a new ultralite alloy code named Shimonium (ok, that last bit was a joke... I think...)

We abide.

Remain In Light.
Is that lighter than unobtanium n/mcurlybike

It's not as light as Polyhomourinate

Which Crampandgoslow innovations would those be?

Indexing--oops Shimano (well really Suntour but who's counting
Integrated Shifting--oops again
Pinned and ramped chainrings--oops
Ramped casettes-hmmm
For that matter Cassettes themselves—not the C company
Freehub--there we go again
Aero Brake cable routing--well!!!
Splined Bottom Brackets--Oh yea Campy tried to copy that for Record and got slapped with a lawsuit for patent infringement

GET THE IDEA? Who is copying whom? I'm not sure Campy has had an innovation since Tullio made the first derailleur. Get a grip, if it wasn't for Shimano's innovation, we would all still be fumbling around with downtube friction shifters, trying to get our Super Record derailleur to stay on the cog on our 7speed freewheels

Finally, I would hardly call a plate in the rear derailleur, shift levers and the BB sleeve a widespread use of carbon fiber in Campy either. OOPs sorry, cannot forget the carbon pull up cap for the aheadset—who was this copied from? Oh yea Dia-compe. That carbon plate in the rear derailleur is a real innovation too, makes a Record 10 a whole 8 grams lighter than a Dura-Ace for only $200 more at retail that is a real bargain in weight savings. You Campy guys got to stop buying bad drugs or maybe it is just mass psychosis.

More Shimano firsts

Floating idler pulley on the rear deraileur.
One key crank removal
Hollow crank arms
11 and now 13 tooth idler pulleys
Dual pivot brakes
Computer functions integrated into shifters.

There is one Campy innovation - absurdly high prices!!

I think the Campy only crowd has been having seconds on that People's Temple Kool Aid. Anyone else feel like the Emporer has no clothes?
Any surprises for this year will be at the show in Oct. n/mcurlybike

You'll be waiting for a while, but XTR '03 will likely bear hints on what's to come. Their new crank and BB spindle will be one solid piece on the drive-side, and the spindle's HUGE, placing the sealed bearings outside of the BB housing, which means super stiff but probably funny-looking. They're keeping mum on how the non-drive side connects, so they must think they have a big surprise for us there as well. They're sticking with 9-speed on XTR, and I continue to think they'd rather stay with it on Dura Ace since Campy did 10-speed first. Don't be shocked if they develop disk brakes for road bikes. The talk is that the new XTR disk brakes hardly weigh any more than their V-brakes and have fabulous modulation.

XTR 03 disc brakes weigh about 980g complete with shifters. Nothing particularly light that you can't get with a current Rapidfire and a third party disc set-up. The non-drive side of the XTR is preloaded with a plastic tool, after wich you tighten the clap bolt on the crank end. It basically clamps in the same way a stem does on a steerer tube.
