All of the current inventory of Dura-Ace 7900 units will have our new Stages Power meter housing which is slimmer, and up to 28-percent lower profile than our original meter. It's sleeker by way of a 17-percent reduction in frontal area, and we've also made it stronger. The new housing design increases the strength of the battery door and housing connection by 200-percent over the previous design.

Pertinent Stages Power Shimano Dura-Ace 7900 model information:

The Stages Power Shimano Dura-Ace 7900 model is cross compatible with all Shimano Hollowtech II road models, from Tiagra to Dura-Ace 9000.

The technology is the same that's found on all Stages Power meters, and as used by Team Sky.

The Stages Power Shimano Dura-Ace 7900 model weighs only 8 grams more than the Stages Power Shimano Dura-Ace 9000 model, and 22 grams less than the Stages Power Shimano Ultegra 6800 model (average weights/actual difference may vary).
