$100 difference in the cranksets - anybody with experience on both? Thanks.
Wait a few months and the prices will be similar.
There’s not a whole lot of difference between the two, obviously. Mainly the R8000 has updated graphics and a beefier crank arm. Far as I know, they are interchangeable, although it would irritate me to have a whole R8000 groupset, and be using an older gen crank.
