The Shimano 7900 pedal bids farewell to the heavier alloy body for carbon. Swapping the alloy body for carbon results in approximately 30 grams of weight savings. This also makes the outstanding pedal design come that much closer to other pedal designs in terms of weight.
When you think of Dura-Ace pedals, reliability, durability and ease of entry/exit and wide platform come to mind. Rarely have we heard complaints except for the weight. The use of carbon will help in this area. They also give the pedal a more contemporary look and feel. The stainless insert on top of the pedal practically eliminates wear - a big problem with other carbon fiber pedals. Triple bearing design is smooth, robust and virtually maintenance free. One screw tension adjustment is simple to use and fool-proof to get the desired release tension. They use the same cleats as the two previous versions, so there is no need to change out all of your cleats if you are already a Dura-Ace pedal user.
Nice and wide and stable for all the steep climbing I do standing. With the new carbon body, they are very attractive pedals. If you dont like the price, you can get basically the same performance from Ultegras.
I too switched from 20 years of Speedplay and am very happy. Easy in and out and enough side play so as not to hurt the knees. Speedplay was great, these are just better, and a heck of a lot easier on which to walk, even if it is just for a drink.
I was a die hard fan of Speedplay for the last 15 years and just switched to the Dura Ace 7900 and WOW. It is like night and day on the amount of contact surface you get. I have been hesitant to buy single sided pedals in the past but the Dura Ace is smooth and easy to get into and the cleat is so easy to walk on its like walking with moutain bike shoes. The one thing I didnt like about the Speedplay is the fact you can feel the pedal through my Shimano 300 shoes and sometimes after long or hard rides my foot was sore the next day. The 7900 platform you cant even tell you have a pedal it becomes one with the shoe. The Dura Ace was 15gms lighter with cleats than my Zero Stainless with cleats. If you suffer from irregular pain and pressure in your feet from Speedplays try a bigger platform pedal like the LOOK or Shimano or Time. It was a hard choice between the Look keo Blade vs the 7900 Dura Ace but the ease of walking on my cleats and durability of Shimano won. Very Happy.
