are all the different series of dura ace 9 speed components compatible? specifically, i have a 7700 series BB and crank. if i were to buy a 7701 crank (or any other series of DA 9 for that matter) is the BB width the same? if you’re really into the tech stuff (and have a few extra minutes) how about a crash tutorial regarding the difference between some of the series? thanks is advance!
7701 & 7700 cranks are the same as far as I can tell, and but both are definitely compatible with the 7700 BB.
All Octalink cranks are supposed to be compatible.
What parts, specifically, do you want to mix?
Yes they are both compatible with the 7700 BB.
The difference between the 7700 and 7701 crankset is the manufacturing process. 7700 were constructed by a welding process. 7701’s were forged.
Different process same cranks.
7703’s are the triple which would require the 7703 BB.
Hope this helps.
IN either case…unless you have real junk…it is not really an upgrade to either from about any crank…unless you have already done your wheels, der’s, pedals, bars and on and on…cranks are about last on my list of upgrades (then again I ride Record Carbon so I shouldnt say anything)
.
thanks for the information guys.
not a question of upgrading, but a matter of possibly getting longer crankarms.
hey, while we’re on the topic, what’s the general thought regarding all the carbon cranksets out there? specifically fsa, or profile elite’s? is there any benefit to them ro just aesthetics? i have full dura ace right now and an undecided about whether to look at a carbon crank or just keep the whole system intact. thoughts?
Even though I justput a set of Pazazz carbon cranks on the Rocket TT7, I see no real advantage except for weight, and you will pay for a significant weight reduction. I merely needed something on my Rocket as my eight year old Sweet Wings finally died. I ended up buying these for $125, and I am glad I only paid $125 for them- they are about 250 grams heavier than my Sweet Wings (w/BB)!!!
You can get some cool shapes with carbon, but only from real carbon, not carbon-wrapped metal (like 75% of cranks on the market). Nobody, except for Stronglight with their Pulsion and Ultim cranks, is taking advantage of cool (or at least interesting with the Ultim crank) shapes with carbon. You will pay for it.
The best carbon crank is the Cat Carbon Bikes Cheetah crank. It is 325 grams and will set you back a little over $750. I have not seen their crank, but have experience with their products and would drop the $700+ in a heartbeat if it would not cause a divorce.
Hey Bunny…my Record cranks are all carbon…right???
Yes. All except the threaded parts (duh).
I do believe so. They had better be for that price.
Yeah, but they will never be the high quality of the older alloy Record ones. The alloy ones were made in Italy. I really don’t know about the carbon ones.
Right on them…Made in Italy…and yes, the Al four arm (polished) are beautiful…but still not as beautiful as the old Mavic cranks…ahhhhhh…even to think about them is nice…and the Mavic BB…ooohhhhhhh…MORE MORE MORE

I think Italian Law allows for an Italian to only have to touch them to be considered “Made in Italy”. So the crates are flown in from Taiwan or China and individually packaged by Tony who puts the “Made in Italy” sticker on them. 2000% mark-up! 
That’s why I asked if they were really made in Italy. On carbon cranks, it’s probably the clear coat and the label.
I just checked…the Made in Italy is under the clear coat…not a sticker…that mean anything? I do think that I saw something that said they were made there is a place that makes parts for Ferrari and such…kinda like Zipp and the carbon starting at the race track…
Maybe they are actually telling the truth, for once.
When a buddy of mine went to Taiwan and saw an expensive “Italian” bike being made in a factory and found out about the lax “made in Italy” laws, I just assume nothing is made in Italy anymore, especially if it’s carpet fiber.
