SRAM's Apex 1 drivetrain provides the gear range and the shifting simplicity to let you simply go where you want. The Apex 1 rear derailleur makes that gearing choice a reality with clean, crisp shifts, thanks to SRAM's X-HORIZON geometry and ROLLER BEARING CLUTCH. Just go: Apex 1 will get you there.
