What Is the Shimano Tourney SL-RS45 3x7 Twist Shifter Set?

The Shimano Tourney SL-RS45 is a 3x7-speed twist shifter set for flat-bar bikes, using a grip-rotate mechanism that lets you change gears without lifting fingers off the handlebar. The set covers front and rear shifting for 21-speed triple drivetrains -- entry-level commuters, casual MTBs, and recreational bikes where simple, affordable twist shifting is preferred over trigger systems. Shift cables are included, making this a complete replacement for worn or broken twist shifters without needing to source anything extra.

Compatible with Shimano 7-speed rear cassettes and 3-speed front drivetrains. Sold as a complete left and right set with cables. Flat bar mount only.
