The Ultegra 12 speed group set is as good as advertised, as long as it is set up correctly you really don�t have to worry about dropping chains or sloppy shifts. I bought the 170mm cranks as it is a better choice for my height of 68.5�, I used both calculations found online for correct crank length. I�ve found it easier to breathe while in the drops compared to the 172.5mm cranks that came with my bike as my legs are no longer contacting my gut. I also believe having the shorter cranks has been good for my hips as well, I was feeling some pain at times from a slight impingement but since using these cranks it hasn�t bothered me. I was slightly concerned about losing some power with the shorter lever but I can still hit my max wattage, I might have to spin slightly faster but it�s not really noticeable.
Switched from 172.5mm to 165mm. Feels the difference right away. My cadence can indeed improve to some extent. Works as expected, no complaint.
Try a shorter crank length. It�s makes a difference in comfort and no difference in power output!
The crankset has a nice finish and a smooth manufactured surface on the cranks and chainrings. This is my first 12 speed product and don't have many miles on the product yet. Installation was easy and once the chain and shifters were calibrated, the crankset operated with little noise and shifted perfectly. I have used Shimano Ultegra on several of my bikes and have had no problems.
I love ultegra crankset, the 165mm is great for my leg length
I use this crankset on my Factor Ostro Vam road bike
reasonably light, solid performance, decent price, all the same features as the top of the line dura-ace product (with only a small weight penalty, but minus the huge extra cost), and in my subjective opinion, a more appealing aesthetic with the matte rather than glossy/polished finish. overall quite satisfied with the purchase, and would buy again and recommend to others!
As with all Shimano cranksets, easy to install and adjust Di2. Finish isn't as nice as Dura Ace, but is half the price and works just as well
