Had to return and order the correct one. ### ⭐⭐⭐⭐⭐ Modifying the cage. *by S***9 on November 27, 2023* CYSKY Bike Front Derailleur 3 Speed - On my old derailleur, I couldn't get the chain to shift to the largest sproket. So, I bought this CYSKY front derailleur. I didn't want to deal with breaking the chain. So, I drilled out the cage rivet. It was hard. The open cage easily went over the chain. I used a stainless locking nut and bolt to replace the rivet. Adjusting is always a challenge but everything went as expected. The derailleur is working above my expectations. I hope somebody will read this and see my picture. I hope this review helps somebody.
