New Dura-Ace Carbon Crankset

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Disappointing that it's not a pure carbon crank. It falls prey to bling syndrome.

For appearance's sake.

Coming from aesthetics, I like the beefy look of the current one.

"We'll be looking very closely at Campagnolo to see how they compare."

Written like a true advertisement. The Campy record crank is 643g -they could have looked that up.

It looks like it's made by FSA.

While 71g lighter than SRAM, it's 60g heavier than FSA K-force.

Kind of a knockoff of the Time RXS. You think they would have come up with something better having so much time to watch the competition.

Duh, nothing like the Time.

You're kidding, right? The look is pure Dura Ace. Very clean.

I can see the similarities... they both have a 5 point spider, both have a crank with threads in the end for a pedal to screw into. Both are shown with 2 chain rings. They each show a name... Yup, exactly the same. lol

The sweep from the spider to the arm is identical, but I'm sure you guys were thrown off by the red stripes.

Shimano makes great MTB groups, but they are long in updating Dura Ace -one would expect something better, like full CF and not a aluminum core, 180mm lengths, compact, lighter, ceramic bearings etc.
Looks nice, but otherwise mediocre compared to others. SRAM is hardly the benchmark.

But at least now we can call Cf cranks a shimano innovation.

It's not identical. It's not even all that close. And since the DA design has been around for about 4 years now, are you certain it wasn't Time copying them?

They already have 180 lengths. Ceramic bearings make great sense from something turning 100rpm.

As far as the full carbon thing, thank you for buying into the ol' "full carbon must be necessarily better" myth. Shimano has the resources to build whatever it bloody wants. If they thought they could bring a full carbon crank to market and keep their position as one of the stiffest, they could have.

No. You can call CF cranks a Shimano innovation. Or whatever you want....

You and Doc Ray are falling prey to the bling syndrome, the aluminum core makes perfect sense. Weight is not always the most important thing when it somes to cranks. If its lighter than the current DA cranks and as stiff or stiffer, I'd say thats a winning combo. Time to get off carbon's dick.

Not any more. so taller riders are SOL.

Yes, they do, enough that many Shimano sponsored teams in the 07 TDF fit FSA ceramic bearings onto Dura-Ace cranks -see this week's Velonews. Sorry, but bearing drag at the crank matters, low RPM, but high force load.

Shimano is world famous for aluminum forging and finishing techniques, and the Ally DA crank is arguably among the best ally there is. But, crank companies like Time, Stronglight, Campagnolo and FSA that have been making CF cranks for years have produced stiff full carbon cranks that are much lighter. Weight is not a myth.
They only made this crank for the CF trend factor. An aluminum core CF crank is just cheaper to make. This is the difference between Chorus and Record.

I guess you don't see any similarity between those chainrings and FSA either.

at least they are up front about the AL and CF mix...

I think it looks better than any crank out...

I hope they still make the AL crank and bring the price down...oh wait that the ultg. SL ...

It actually looks kinda like the Cannondale's carbon fiber crank arm.

there is more than meets the eye:




The pedal insert is not like other designs that come unbonded, the arms are hollow.

In honor of the recent trend of comparing two completely different cranks;

That looks EXACTLY like a Sugino 75!

Sux it's not being made in 177.5 or 180 lengths. Shimano is making it harder for me to stick with DuraAce.
