Recently upgraded to a GRX front derailleur and crankset to get rid of some tire rubbing issues I was having with an older dura ace front derailleur. Problem solved with the upgrade but I wish Shimano made an option to purchase together with the derailleur instead of separate parts.
You don't want critical components of your bike to fail while far away from your car. This clamp is critical to mission success. It is built to the exact standards that will not fail you.
