My main bike has a Shimano GRX 46/30T crankset, with either an 11-34T or 11-36T cassette (with an Ultegra derailleur officially rated for 32T max).
My Campy bike has an Athena triple, with the smallest of the 3 chainrings 30T (and largest is 52T). The cassette goes up to 29T (with an Athena long-cage derailleur). That doesn't get me as low as the "main" bike, but it is significantly better than what I had in 1987.
