SRAM MRX Comp 8-Speed Shifter Set — Rear Microfriction + Friction Front, Lightweight Durable

The SRAM MRX Comp shifter set is an 8-speed rear microfriction shifter paired with a friction front shifter, supplied with inner cables and stationary grips for ready installation.

This compact shift kit combines a precise indexed rear unit with a flexible friction front to give riders reliable gear control across 8-speed drivetrains. Built with a grilon composite body and a speed-release spool with internal assist spring, the set is engineered to be durable, lightweight, and compatible with a wide range of front derailleurs from both SRAM and Shimano.

How does the rear microfriction shifter improve shifting on trails?

The microfriction rear shifter provides indexed clicks for each of the eight cogs while offering fine control to prevent overshooting under load. Its internal assist spring and speed-release spool help the cable move smoothly so shifts are crisp even when the drivetrain is dirty or under tension.

• Indexed 8-speed engagement for predictable gear changes
• Internal assist spring reduces missed shifts and cable drag
• Speed-release spool for fast, reliable downshifts
• Grilon composite body keeps weight low while resisting impact

Will the friction front shifter work with my front derailleur?

The friction-style front shifter is intentionally non-indexed, so it pairs with most front derailleurs from major brands, making it a versatile choice for double or triple chainrings. The lack of indexing removes brand-specific tolerances, letting you fine-tune front shifting with simple thumb control.

• Compatible with SRAM and Shimano front derailleurs
• Works with double and triple chainring setups
• Easy to micro-adjust for precise front shifts on climbs
• Stationary grips included for a complete replacement or upgrade

What comes in the kit and how straightforward is installation?

This package includes the MRX Comp rear microfriction shifter, a friction front unit, inner steel cables, and stationary grips so you have the main parts needed for a full handlebar-mounted shift setup. Installation is beginner-friendly for most cyclists familiar with cable routing and offers a quick upgrade path without special tools beyond common bike tools.

• Rear and front shifters included for matched ergonomics
• Die-drawn steel inner cables supplied for immediate fitment
• Stationary grips to mount and finish the cockpit cleanly
• Standard cable routing fits most mountain bike frames and derailleurs

Who is this for: The SRAM MRX Comp shifter set is aimed at riders seeking a low-weight, durable shift solution for 8-speed mountain bike drivetrains who value dependable indexed rear shifting with the flexibility of a friction front. It's well suited for commuters, budget-conscious mountain bikers, and anyone restoring or customizing older 8-speed bikes where compatibility and straightforward installation matter.
