PaulGreat quality product for top of the range gravel bikes
Mr AMIThis derailleur works great. However not happy with Shimano for forcing me to buy it. I have a 2016 gravel bike with Di2 shifting and a 50-34 compact crankset. I wanted to change it to the newer GRX 48-31 for easier pedaling up hills on local gravel roads. Shimano changed the crankset just enough to make the new crankset not compatible with my current derailleur. At least they made this derailleur compatible with my current shifters.
