Description:
Designed during Shimano’s aerodynamic styling revolution of the early 1980s, the Shimano 600 AX SL-7300 shift levers present a radically streamlined approach to gear selection. Mounted to a dedicated 28.6 mm band clamp for steel downtubes without braze-on bosses, these shifters feature flush, wind-tunnel-modeled tensioning screws and slender lever blades. They provide silky-smooth, precise friction actuation across 5- and 6-speed clusters while drastically reducing wind resistance on classic racing setups.
