Wow! Those look interesting.
When I looked for TI spindles for dura ace before, they didn't exist.
I am a little skeptical, because on the DA design the bearing race is actually on the spindle, which is a good reason to use hardened steel. But if the TI wear for a significantly length of time at all it might be worth trying.

I have ti spindles in my 6700c pedals. They were 6700 spindles from "ti-spindles" in the US, which we took some material off to match the shape of the slimmer 6700c spindle. Weight is 216g, so I imagine DA with ti would come in at 210g.

Kind of begs the question; why didn't Shimano use Ti in the first place? Plenty of others do.

Longevity? Avoiding having to put a weight limit on? Price? (I reckon for a 50$ premium, there'd be plenty of takers).

Because the bearing system uses the axle as the surface the balls roll on, rather than just being what the inner race of a cartridge beating sits on, therefore the material used plays more of a part in the performance

therefore Titanium axle with piece of steel insert only at contact point which work as inner race of bearings would make it better, right?

I'm going to put my two cents in to Look Keo Blade carbon. I rode time before.

the looks give me a better range of cleat adjustment options. the TI spindle version is light enough for me and I like the feel of the tension and the float.

Certainly. This would be a rather complex titanium-steel arrangement however, due to the nature of the Dura Ace bearing arrangement, requiring 3 steel sleeves, to handle the 3 bearings contact points (one of which is a long needle bearing) so it might not end up saving much weight. On the 9100 the needle bearing is gone however, so it could work out better on these new ones.

Ok, i switched few rides ago on Look Keo2 Max Carbon pedals (i bought them last season, just to test Look system). Also wanted to test which tension is good for me and since i ride two clicks In from the lowest settings, i guess this is comparable to Look Keo 2 Carbon 12Nm (good i tried, as first i think that 16Nm will be the right one).

But please someone confirm me this. If i ride Look Keo2 Max Carbon two clicks in from the lowest setting, i need 12Nm or 16Nm Look Keo 2 Carbon?

And i can see 2017 version of Keo 2 Max Carbon Ti, beeing cheaper then just Keo 2 Max Carbon Ti. Is there any difference at all between 2017 version and older version ?

Now let me compare Look Keo2 Max Carbon to my Time:

- Clip In

Its definetly easier on Time Xpresso, but maybe im not used of this Look (since i ride them only for last 300 km).

The problem i have with Look is that they are always on wrong side, so i need to look down to find where to clip in. I guess i'll get used of it after more riding.

- Clip Out

On Time it's to easy for me, and i have often cliped out when i dont want. On Look its better. There is a moment when u know u are clipping out


- Whole feeling

Seem that i prefer Look vs Time. On Time when i push hard, i hate that lateral movement, and also sometimes i feel like this take some of my energy in that movement. On Look its stiff feeling, and i can feel whole my energy is going where should be going.

On Time it's easier to setup clits to dont have knee pain, on Look first ride i had some pain, but i adjusted very easy and now everything fine (im using 4.5 degrees gray cleats).

- Creaking

On Time no Any Creaking, on Look first ride i had some, but on last ride (134 km), no creaking at all.

- Walking

I have fer meters i need to walk until i start riding (like 10-15 meters). Better waling on the look cleats, and also seem that Look Cleats will last much more (on Time this is the weakest point. I was buying new cleats every 1500 km, max i rode was 3000 km but in reality i should replace them much earlier).

I'll give few more rides, but until now seem that i really like how Look Keo system works. If this continue in few more rides, ill switch to Keo Blade 2 Carbon Ti, since they are very light. Just hope that they'll have the same feeling as Keo Max 2 Carbon im riding now.

Another thing why i wanted to test Look setup, is because of powermeters based on their cleats. Very interested in BePro Pedal based Power Meter

The place I ordered my Dura Ace pedals where out of stock so I wound up with the Look Keo Max Blade carbon ti. 183 grams for the pair and no issues in about 200 KM of riding. Still have Xpresso's on the tt bike but may change if the Blades are still to my liking in a few more months. I really wanted to try the Dura Ace but the weight of the Looks made the decision change by me okay.

The DA pedals are butter smooth compared to what I've experienced with Look KEO blade pedals.

Time still makes the old RXS pedals. And that is not without reason! It is still their best pedal but they "had to" come up with something new. I went from shimando's ultegra, DA to Time rxs because: they are very light, the cleats last forever, no horizontal play (or how do you call this?) because of wear and they are very reasonably priced.
I had to get used to the immense float but now it feels very nice. No worries for knee injuries and not so critical alignment.
Newer isn't always better....
Oh, it's all right. I'm sure that we can handle this situation maturely, just like the responsible adults that we are. Isn't that right, Mr... Poopy Pants?

Exactly, and the Young's modulus of Titanium alloy is quite low, making it less than an ideal bearing surface.

I use Look Keo 2 Blade..

After using 2 weeks, it started creaking..

Yep... bought Time rxs.

Use normal cleats and not the 'grip' version.
