Quarq DFOUR RED E1 cranks on Shimano Dura Ace 9100 install, weight, fit.

Wanted to try out an other better power meter (double sided, kind off) a bit shorter cranks with the same weight or less than Dura ace cranks in combination with a 4iiii power meter, which takes Dura Ace rings for perfect shifting and esthetics. Hardly notice the crank length difference. Cranks a bit stiffer, power meter more accurate.
Shifting still great. Sram is more of an installation hassle and the bottom bracket lasts only for so long, let's wait and see.
