|I am currently running 105's and they are a little flexy. I am a clydesdale so does anyone have suggestions? Ultegra, D/A or maybe something Italian?|

|The new DA10 are supposed to be the stiffest available. People are also saying that they will work with the older Shimano 9speeds. You might want to look at that.
I do not have first hand experience, so this is all second hand info.

|Whether the stiffness differences between top cranks are meaningful is another question. Also, I wonder how people can separate the stiffness of their cranks from the stiffness of their frames, pedals, or even their shoes.|

|These "stiffness" tests are meaningless in the real world. Have you ever seen how they do it? They put the crank in a vice an apply pressure against the other end of the crank. Then they measure the amount of flex. That's all good if your frame and BB are as stiff as that vice mounted to a table! But they aren't. Besides, the amount of flex between different models of cranks would not be detectable to a rider in the real world. How can anyone feel even 1mm of flex in a crank? You can't. I have three different bikes one with Campy C-Record one with Dura Ace 9 speed and one with Campy carbon. I have also used the Campy 10 speed aluminum crank and the Carbon Lord carbon fiber crank. There is absolutely no difference between any of them. If you perceive flex it is most likely coming from the frame since it supports the most weight and transfers the most power.
Now someone will ask why I bought the carbon cranks over the standard ones if there is no difference. The answer: Because I like the way they look. Plain and simple.

|When I first put my D/A cranks on I could tell a little difference between them and the last set. After about the first few rides, I stopped noticing it.
I'll let you in on a philosophy I've tried to live with for a while now. Its called "the Tom Greaves biggest gnarliest principle." Basically, buy the best thing you can afford because in the long run, it means you don't have to upgrade as often.
Hope this helps.

The "Greaves principle" is probably the best advice I've received. I have a similar principle buy what you want the first time and you do not have to buy it again later. Alas had I followed that this whole discussion would probably be moot

|Yeah, well, hindsight is 20/20 right?

|According to a German test DA10 have the same stiffness as 9-speed DA. Meaning, Cannondale SI Hollowgram cranks are still the lightest and stiffest system available...the only catch is you need a specifically adapted frame to mount the BB system. I'm sure Seven, Moots, Litespeed, or any other custom builder of choice, would be happy to help you fit one for the right price in case you don't like a Cannondale:)|

|I just switched from dura ace, and they are noticably stiffer. I am 6'0" 195pounds.|

|I have switched to the new 04 M760 Shimano MTB cranks. My MTB bike had Truvativ cranks. The difference was obvious. I realize when someone says that the flex could be elsewhere (frame, etc) and that small differences can just be perceived differences, but the Shimano M760's obviously stiffer, I guarantee that.
As for the 04 DA cranks, can anyone say they have tried them and they are compatibile with 9 speed? I cannot afford the full upgrade recommended (chain, shifters, deraileurs, cassette, BB, cranks).
I currently have 03 DA cranks on my Specialized S-Works. I am not saying the 04 DA is defintely stiffer than 03, but I am willing to try the 04 after experiencing the Mtb difference. I will post if I truly believe they are stiffer when I can afford the cranks (hopefully sometime shortly after the holidays).
