Shimano has redesigned the 105 line of components to keep it up to date with the ever-evolving industry standards. The R7000 utilizes trickled down technology from Shimano’s top-tier groupsets, taking upon only the best of features to provide you with a budget-friendly yet race worthy drivetrain you can trust even under the most demanding conditions.
The Shimano 105 FC-R7000 Crankset features an optimized lightweight and stiff crank arm that provides excellent power transfer efficiency. The R7000 crankset also features a redesigned chainring tooth profile to increase the clearance between chian and leading teeth to provide compatibility with frames with O.L.D. 135mm and 410mm chain stay lengths.

I bought a "new to me" Cervelo R2 and wanted to upgrade the crankset from the original Shimano FC-RS510. I was looking at the Ultegra R8000 crankset and decided to go with the 105 R7000 to save the money. The Ultegra is only 100 grams lighter than the 105 and with the other great reviews of the 105, I couldn't justify spending the extra money for the lighter weight crankset. The 105 R7000 crankset is lightweight and strong. It was an easy and quick replacement and after adjusting the front derailleur, I was back to riding. I plan on replacing the chainrings with Rotor Q rings and my only complaint is there are not any 105 specific bolts to provide the fairing of the crank to the rings like the Dura ace and Ultegra have available.
