There's even fewer differences between the 105 pedals and Utegra pedals. Only 10 grams in weight, and basically exactly the same materials/bearings. So if u have to use Shimano SPD-SL system, either get 105 or Dura Ace.
@bengt_axle3 ай бұрын
The Dura Ace pedals have an extra bearing on the medial side of the spindle. This is why there is a bulge in that area, as opposed to just wrench flats on the pedal spindle. If you are putting down sprint watts, then the Dura Ace pedals will better resist flexing of the spindle and pedal body.

I use their predecessor, the PD-A600. Once worn in, do the ES-600s end up balancing at a nice angle for engagement? The A-600s are almost impossible to find nowadays, and I know someday I may have to change.

Yes, that's the official numbers from Shimano... I was trying to figure out how they came to that number without much luck. But I reckon it's including the cleat (Which is probably the number that's useful to be fair😅) I was trying to figure out the difference between pedals alone, ie center of pedal axle to the plaform of the pedal. Poorly executed nevertheless hehe

Stack height doesn't matter for non pros. The actual real world efficiency benefit is negligible. And even pros don't pedal through corners. Look at any racing sport that uses tires, there are no examples where the racer or driver accelerates through the entire corner. Tires can only withstand a certain amount of lateral/vertical load. When accelerating through the entire corner, there is a risk of the tires slipping, i.e. exceeding the maximal load the tire can withstand. In cycling, lean angle and tire kinetic coefficient are much more important in cornering than stack height. Stiffness is another story. Dura Ace may win on that front.
@mseekles1972Күн бұрын
@@brittle1how does stack height help you pedal through corners? It does not influence how low / close your pedal is to the ground. Isn’t your q factor more important for that? The dura ace pedals have a smaller Q factor, give you a smaller stance.
@barrowsworm12262 ай бұрын
The big differences with D-A over Ultegra are: the improved bearing design, and the lower stack height, these things matter for performance. If weight is your primary concern, consider the top level Time pedals. I saw the Xpedo SPD-SL pedals, looks like there is little room in the spindle for any kind of a decent bearing set up: I would not be surprised if those Xpedo pedals suck watts under pedaling loads without good bearings.

I did this exercise with the bolts and was also disappointed. One even worse detail is the tip of the "DA" bolts are chamfered so you effectively get a shorter bolt than the standard, making it harder to get engagement on the threads in some cleat positions. Especially with new cleats and new shoes

A benefit (or handicap, depending on how you look at it) of the Dura Ace pedals is that they come with adjustable preload on the bearings, and their bearings are the cup and cone variety, not cartridge bearings as in the Ultegra pedals.

Ti bolts and washers come in at around 20g for a set vs around 34g for the default Shimano steel set. I went s-parts but there are a few brands. Cost about $40. Xpedo SONIK Ti is SPD-SL at 188g claimed. The Ultegra pedals you showed look authentic but be aware many of the cheap ones are counterfeits made in china instead of japan. The counterfits seem to come in at 250-265g and historically the axle nut was a bit different. For forbidden upgrades: Both Dura-Ace (17 & 9) and Ultegra (12 & 12) use loose steel balls. With a Ti axle Ultegra can have 1 of 4 bearing race interfaces as steel on Ti vs Dura-Ace 2 of 4 which will be more prone to wear. Some people are now using cerakote to better protect the Ti axle. Ultegra with Ti spindles is 205g.

Surprised you didn’t disassemble and show the bearing/axle difference. That is what you pay for along with a three year warranty. Very often durable ace is heavier like the older front derailleurs but stronger and more robust. Weight per dollar is an odd measurement on such a critical component.

Titanium is not a fitting material for bearing races. Because that is what those axle also are. Surely you can swap them, but it wil just wear out very fast, roll with substentially high drag the whole time and you will probably just brake them off, which you can consider yourself how dangerous would be for your riding.

SPD-SL is kind of a scam. The world never needed SPD-SL. The only time Dura Ace pedals were something special is when they had needle bearings. Now they dont, and it makes them even more of a scam. The whole pedals interface general understanding among most cyclists is very misguided and understood.., well - wrong. The correct material for the best solution of clippless pedals is metall. Not plastic. Best in many and most terms. Also in terms of weight. Shimano is actuallly making some of their SPD pedals heavier on purpose, because it would otherwise weigh less than the DA. Also, when talking about weight of pedals, one needs to measure the whole system. So pedals+cleats+fasteners. That is the only correct way. Oh, and the bodies of those pedals are not carbon. It is carbon reinforced thermoset plastic. It has little to do with carbon in terms of structural material properties.
