The redesigned Shimano 105 FC-R7000 crank balances weight and efficiency without sacrificing stiffness. Its wider gear pitch increases clearance with small gearings on modern 135mm O.L.D. frames.

I bought these 160 mm Shimano crank arms to replace the original 170 mm cranks that came with my bike. These cranks were a simple install. I used Shimano's torque guide to ensure all the screws and bolts were properly tightened.
I bought these for a size 49 frame Trek Domane to better fit the small frame and my smaller size. I get much better power transfer with these shorter cranks, especial during cold starts. I used to climb steep hills in the lowest gear but now I can climb the same hills in 3rd gear. My average RPMs tend to be higher now but that's not a problem. My average speed may have changed a small amount but mostly there is just a very noticeable improvement in the quality of my rides.
Two different cranks size calculators suggested I use 157.5mm cranks but these cranks were the smallest size I could find. I'm really glad I found them. The difference 10 mm makes for me is dramatic.
