What is the Shimano ST-EF500 brake/shift lever set?

The ST-EF500 is Shimano's EZ-Fire Plus integrated brake and shift lever set for flat-bar bikes. This 3x8-speed version suits recreational MTBs, commuters, and hybrid bikes running a triple chainset with an 8-speed cassette -- a drivetrain configuration that provides maximum gear range for riders on varied terrain. EZ-Fire Plus allows upshifting and downshifting from the same lever position, keeping operation simple and intuitive across all 24 gear combinations.

Compatible with Shimano 8-speed cassettes and 3-speed front drivetrains. Left lever controls front derailleur (3-speed), right lever controls rear derailleur (8-speed). Brake cables included.
