Shimano Dura-Ace FC-R9100 165mm 53/39T 11 Speed Crankset

Featuring superb Japanese workmanship and a highly polished near black-to-pewter finish, the Dura-Ace ethos can be immediately identified with one quick look. The 2nd Gen, 2x11-SP Dura-Ace FC-R9100 Front Crankset has a distinct asymmetric 4-arm design and the driveside arm has been augmented within the same asymmetric bolt circle pattern. Width and size were added to the drive side arm for optimal power and efficiency in the most crucial phase of the pedal stroke and might have caused weight issues but for the benefit of Hollowtech II technology to manage that while still maintaining the strength you need for better power transfer and more precise front shifting. This particular model features a crank arm length of 165mm.

The teeth of this 53-39T chainring have also been re-engineered for greater efficiency, reduced friction and wear, and faster, quieter shifting performance (with mechanical or Di2 systems). The reconsideration of the tooth profiles was also driven by the more extreme chainlines found on today’s shorter chainstay frames, which when combined with greater cassette range and new rear spacing, totally changes the load the chain must manage for safety, as well as shifting performance. This, and many more benefits, will come to your attention once you’ve mounted and used the crankset a few times. One thing is for sure, if you thought reliable, high-quality bike components were a thing of the past, think again.
