The Giant Revolt Advance 3 has a frame that will take up to 53mm tires. It comes with a 2x10 that has a road derailleur on the front and a GRX on the back. The stock front derailleur interferes with the tire for any tire bigger than 40mm.
The GRX front derailleur solves this problem and allows the largest tire size that the frame supports. I am running 29x2.0 now.
One complication is that the maximum chainring is 46 tooth, so I had to get a new chainring also.
This style derailleur was new to me. I found a good video on YouTube to help me get started.
