SRAM, MRX Comp, Gripshift shifter Pair, 7sp

The SRAM MRX Comp 7-Speed Gripshift Shifter Pair is an entry-level twist-shift assembly designed specifically for older mountain bikes, recreational hybrids, and kids' bikes. Like its 6-speed counterpart, this shifter utilizes a Shimano 2:1 actuation ratio, enabling it to deliver clean indexing shifts when paired with common Shimano drivetrain components.

Core Technical Specifications

• Configuration: 3x7 Speed Pair (Includes a 3-speed micro-adjust left-hand shifter and a 7-speed indexed right-hand shifter).
• Actuation Ratio: Shimano 2:1 cable pull standard.
• Body Material: Durable Grilon® composite with soft, textured dual-density rubber grips.
• Internal System: Built using SRAM’s Speed Release Spool (SRS) technology to minimize mechanical shifting effort.
• Cables: Includes inner die-drawn steel gear cables pre-routed inside the housing mechanics.

Drivetrain Compatibility

• Rear Derailleur: Syncs perfectly with 7-speed Shimano mountain and hybrid rear derailleurs (e.g., Shimano Tourney TY300, Altus, or older Acera/Alivio models).
• Front Derailleur: Triple-ring micro-adjust friction logic matches smoothly with both Shimano and SRAM front derailleurs.
• Incompatibilities: Completely incompatible with SRAM 1:1 actuation rear derailleurs (e.g., SRAM X3 or X4 line) and newer 1x11 or 1x12 mountain platforms.

This product is an excellent choice for those looking to upgrade or maintain older bikes while ensuring reliable and smooth shifting performance.
