The Shimano Tourney ST-EF41 Shift/Brake Lever Combo (3x6 Speed, Black) is an integrated cockpit component designed for budget-friendly mountain, hybrid, and city bikes. It combines a 3-speed front shifter, a 6-speed rear shifter, and a 2-finger brake lever into a single handlebar clamp assembly. This configuration helps clear up your handlebar space and reduces weight compared to standalone units.
