The Z4 is made in the same mold as our top-of-the-line Z1 to offer the same stiffness and performance, even for a rider who is cost-conscious. The selection of SRAM Apex and Rival components includes a compact crank and wide-spaced cassette to give you gears for any road, no matter if it’s steep or flat, while preserving snappy shifting. Whether your goal is your fastest time at a gran fondo or your first podium finish at a race, the Z4 will take you there.
