Shimano Shimano Double Ring Crank 2x10 FC-7900 (Dura-Ace)

I've used previous models of Dura-Ace starting with the classic 7400 series. I've also used Ultegra model 6500 and lastly Campy cranks over the years and by far this model of Dura-Ace is the best.
The 7900 crankset is the sleekest and lightest...yet very strong with no flex in the arms, which slice through the air with an aerodynamic profile.
The finish is flawless, similar to the previous model 7800. The hollowtech II design with the outboard bearings make installation and maintenance a breeze (just two Allen keys and bearing tool).
The large chainring has design features which help make shifting from the small chainring to the large chainring smooth and crisp.
You will be very happy with the upgrade or choice as original equipment.  Less
