Shimano 105 R7100 12-Speed Crankset
The Shimano 105 R7100 12-Speed Crankset is big on performance but low on price. The R7100 is finished with a durable, anodized gloss black coating while the HOLLOWTECH II structure reduces weight. In additions, stiffness is maintained for maximum power transfer. This crankset is available with 50/34T or 52/35T chainrings, which when paired with Shimano’s 12-speed cassettes provides ideal gearing for most road terrain.

I’m thoroughly impressed with my Shimano 105 R7100 12-Speed setup.
This is my second 105 Crankset and it was acquired so I could experiment with different crank lengths.
The whole system works flawlessly as intended and the finish quality is excellent.
The ordering process was seamless, and I was thrilled to receive my crankset promptly.
Power Meter City’s customer service and shipping were top-notch, making this a hassle-free transaction. I highly recommend them to anyone in the market for cycling gear.
For the price benefit ratio five stars isn’t enough!
