2004 Shimano Dura Ace Crank Compatibility(8 posts)

I have heard, as have others who I have seen post here that the 2004 DA Crank is compatible with the DA 9 speed group. Anyone know or want to offer their opinion on this?

I will not be able to afford the entire 10 speed group change recommended by shimano anytime in the near future. If I am lucky I can get the crank and BB in about 3 months, but I would prefer to hear some positive results by others before making this investment.

I dont see how Shimano would be any different.
Whats wrong with your current cranks anyways?

To be honest, nothing. I am 6'2" 235lbs. One area I am always looking for improvement is the stiffness in the BB/Crank.

If the 04 Crank does nothing, I might look at my frame. The only frame I think that would be stiffer than the Specialized would possibly be a Cannondale, but I have found the Specialized very ridable not jaw shattering like most aluminum road frames I have been on.

I am also not ready to move to the aluminum w/ carbon seatstays until I am sure of the reliability. Seems every manufacturer is doing it, probably due to the low cost to performance ratio.

that the new DA cranks are very stiff!
That would be a good reason to upgrade.
I also have heard from friends that ride the new Specialized M4 that it does ride very nice.
At 235lbs It would be hard to find something that is stiff.
I can feel things flex some and I am only 150lbs. I can only imagine what you are feeling.

OK, it's probably the same question, but I was wanting to try the new shifters due to the improved ergonomics and brake reach. I also cannot afford the group, but have no knowledge of crossing the different speed systems.

Anyone running different speed shifter and derailleur?

Thanks!

The Shimano rear derailleurs are all the same throw, but the 10-speed shifters pull less cable per shift to match the closer cog spacing of the 10-speed cassette. So, if you want the shifters, you'll also need the 10-speed cassette ($$$) and a narrower chain. The 9-speed derailleurs and crank should work.

I'm getting the DA 10, but I'll be glad when they come out with an Ultegra-level 10-speed cassette. I don't like paying so much for consumables (tires, chains, cassettes).

the chain is narrower on the outside, but not on the inside, so the cranks should be 100% compatable.

Just put the cranks last week. Didn't change the front derailleur or chain as shimano site recommends(FAQ), but I haven't noticed any problems. So go ahead and pop em on.
