Product Details

Overview & Technology

SRAM NX brings proven SRAM shifting tech to a value-minded 11-speed MTB derailleur. The X-HORIZON parallelogram keeps the top pulley in a controlled, linear path to reduce shift force, eliminate ghost shifts and improve chain security over rough terrain. Combined with X-ACTUATION tuning, you get crisp indexed shifts across the cassette with minimal rider input. The derailleur features 12-tooth X-SYNC pulley wheels and a Roller Bearing Clutch for consistent chain retention and reduced chain slap. Built for real-world trail use, the NX balances durable materials and serviceable design so you can expect reliable performance mile after mile.

Key Features & Construction

The NX derailleur packs SRAM's signature technologies into a robust package. X-HORIZON stabilizes the upper pulley path, X-SYNC 12T pulleys optimize chain engagement, and the Roller Bearing Clutch maintains chain tension on rough descents. CAGE LOCK makes wheel removal and installation easier by locking the cage forward. This long-cage model supports a wide 32T capacity and handles cassettes from 10T up to a 42T largest cog. Materials and construction are chosen for durability: precision-machined linkage and a reinforced cage provide long service life while keeping weight competitive at 322g.

Fit, Compatibility & Specs

The NX rear derailleur is designed for SRAM 1x drivetrains and indexed 11-speed systems. It uses a standard mount and long cage to support single-chainring setups with a maximum sprocket of 42T and total capacity of 32T. Ship weight and boxed dimensions make it a compact upgrade or replacement: 322g listed weight and shipping dimensions 6.8 x 6.6 x 3 inches. Key specs at a glance: 11-speed, long cage, 10-42T compatibility, 12T X-SYNC pulleys, and Roller Bearing Clutch. While optimized for SRAM 1x systems, this derailleur is not intended for SRAM 12-speed AXS electronic setups or for mixing with incompatible shifters without proper matching of actuation ratios.

Who This Is For

This derailleur is ideal for trail riders, all-mountain enthusiasts and commuters who want reliable 1x shifting without the premium price tag. If you ride mixed terrain, carry a bike for long days out, or need a durable replacement for a beaten-up part, the NX offers predictable performance and straightforward maintenance. Choose the NX long-cage if you run wide-range cassettes, bikepack with variable loads, or prioritize chain security on technical descents. It's especially well suited to riders upgrading entry-level builds or maintaining a solid budget-friendly trail rig.

Frequently Asked Questions

Is this derailleur compatible with SRAM 12-speed systems?

No. The SRAM NX listed here is an 11-speed mechanical rear derailleur built for SRAM 1x 11-speed actuation. It is not compatible with SRAM 12-speed AXS electronic systems or 12-speed mechanical ratios.

Can I use this with Shimano shifters?

SRAM 11-speed mechanical derailleurs require SRAM shifters with SRAM's actuation ratio. Mixing with Shimano shifters typically results in poor indexing and is not recommended. Match SRAM shifter and derailleur for reliable performance.

What cassette range will this support?

This long-cage NX supports a minimum 10T small cog and a maximum 42T large cog with a total derailleur capacity of 32T. It's ideal for common wide-range 11-speed MTB cassettes.

How do I service the clutch and pulleys?

The roller-bearing clutch is durable but benefits from periodic inspection and light lubrication per SRAM service guidelines. X-SYNC pulley wheels can be serviced by removing the cage and replacing bearings or the pulley if worn. Regular cleaning and grease on pivot points will extend service life.

What are the benefits of X-HORIZON and CAGE LOCK?

X-HORIZON stabilizes the upper pulley path to reduce ghost shifting and lower shift lever force, giving crisper, more predictable shifts. CAGE LOCK swings the cage forward and holds it there to make wheel removal and chain routing faster and easier when you change a tire or remove the rear wheel.

Is this derailleur good for bikepacking or loaded touring?

Yes. The long-cage capacity and clutch retention make it a solid choice for bikepacking or loaded rides where chain tension and gearing range are important. Just ensure your cassette stays within the 10-42T max and total capacity of 32T.

Buying Guide

When choosing a mountain bike rear derailleur, match speed and actuation first: an 11-speed SRAM derailleur needs SRAM 11-speed shifters. Decide on cage length based on cassette size and total capacity — long cages accommodate wide-range cassettes and loaded setups. Look for a clutch-equipped derailleur for better chain retention if you ride rough terrain or carry baggage. Consider construction and serviceability: sealed bearings, replaceable pulley wheels, and a robust parallelogram design extend lifespan and simplify maintenance. If you prioritize low cost with reliable trail performance, the SRAM NX long-cage 11-speed derailleur is a practical, easy-to-service choice.
