Shimano Tourney SL-RS45 3x7-Speed Twist Shifter Set

What Is the Shimano Tourney SL-RS45 3x7 Twist Shifter Set and Who Is It For?

The SL-RS45 3x7 is Shimano's Tourney-series Revo twist shifter set for triple-chainring, 7-speed rear drivetrains on flat-bar bikes. The set includes left and right shifters in a paired unit: the right shifter controls rear derailleur indexing across 7 positions, and the left shifter controls front derailleur indexing across 3 chainring positions. Both shifters use Shimano's Revo twist mechanism, where the grip rotates forward and backward around the bar to execute shifts rather than using a trigger finger. Twist shifting is a style preference that some riders find more intuitive for casual and commuter use, particularly those migrating from scooters or motorcycles, or younger riders who find trigger mechanisms less natural. The set includes a SIS40 shift cable set so both cables are ready to install at the same time as the shifters, avoiding a separate hardware order. An optical gear display is built into each shifter body, showing the current indexed position as a number visible during riding.

The SL-RS45 mounts to standard 22.2mm flat handlebars and is compatible with Shimano's SIS indexed shifting system for 3-speed front and 7-speed rear derailleurs in the Tourney lineup. Stationary grips are not included and must be sourced separately. For riders building or restoring a 3x7 commuter, city, or basic flat-bar MTB drivetrain and preferring the twist-shift control style over trigger levers, the SL-RS45 is the correct paired set at the Tourney tier with cables included.
