I'm seeing reports of mixed results using the GRX crank with road front derailleurs - has anyone done this with their Renegade? I have the matching GRX derailleur if needed, but it's a braze-on mount and my existing derailleur is a band clamp, so if the current derailleur doesn't work I'd need an adapter. It would be great to know in advance from other Renegade owners if this is likely to work, so I don't install the new crank, find it doesn't work, and have the bike out of commission for a few days while waiting for the adapter to arrive. Thanks for sharing your experience!
I’ve also read reports of road FD with GRX crankset - but I went with a GRX FD when I installed a GRX crank on a Topstone
I used Shimano front derailleur band adapter SM-AD91 to mount the GRX FD
