2004 Dura Ace Group predictions?(16 posts)

2004 Dura Ace Group predictions?gregdogg62

I was just recently reading on the predictions for the changes to Dura Ace in the future. What do you guys/gals think the major changes will be?

10 speed?
Carbon galore?
internal gears
I hope nonepmf1

Its a pretty good group as is. They could redesign the bottom bracket. I could see carbon cranks on the way, but hopefully they would be an option like they are with Campy. DA cranks are pretty nice (light and stiff). Personally, I don't see a big advantage between 10 speeds versus 9, although I'm sure some folks do. In all honesty, I was happy with 8. Its interesting that Shimano didn't hop on the 10-speed band wagon right away. I was suprised.

I've always been happy that Shimano resisted changing the group every year or so with questionable improvements like Campy did. I'd be a little POed to spend big bucks on Record and then see it become Chorus the next year to make way for carbon levers or a light weigh brake. Almost a reversal in marketing strategies between the two.

How narrow can chains get? Going beyond 10 speeds without changing bike geometries doesn't seem possible. I'd really be unhappy if that happened.

No, do something for the mashers not the spinners. How about a 42-53-63-72 front combo.

My one lbs was trying to sell me a road bike two months ago and gave me some insite. He said shimano is working on a 12 speed groupo for 2003. Not sure if its in the testing period.

Has anybody see it on any pro racers bikes this year?

I've heard this 12-speed rumor for several years now. Probably all it is.

That would create some hell a steep chain angles if you had a triple up front. How small do they think the can make a chain and still maintain its integrity. Not to mention the same gear ratios in the different chain rings.

My bet.....muncher

10 Speed. But in addition, and for no apparent reason, a load of small, un-needed, changes to BB widths, splines, ratios and whatever else they can dream up to screw compatibility and whap up parts prices?

Cynical? Moi?

When they went from 8 to 9 speed, everything stayed compatable. It was a very un-Shimano-like move at that time. I remember when 9-v came out and I thought, oh crap, look at all the obsolete wheels I've got. I was over-joyed to see that a 9-v cassette worked on my 8-v wheels.

8 and 9 speed cranks and bottom brackets are not interchangable. Otherwise though, compatibility was decidedly un-Shimanolike in that transition.

You could use the 9-v set up with the 8-v cranks and with new rings if you wanted to. I think the splined BB really is an improvement. I just wish it wasn't patented so other companies could make it. Changing a cassette body is another thing. And it did amaze me that Shimano did not do it.

From a semi-reliable source. Shimano never went 10 because Campy had patents....which run out in 2003. Shimano also has a 14-speed patent( you can do a search on this )with a single front chainring. Shimano has working proto's of both these designs. Incidentally, keep an eye on Campy's chainrings next year as Shimano ramped and pinned chainring patent expires and I wouldn't be suprised to see Campy copy these.
