Product Details

Overview & Technology

SRAM NX 1x11 B-Adjust and Limit Screw Kit (SRAM Model ID: RD-SPP-A0, MPN 11.7518.067.000, Product #270930) is a compact replacement kit engineered to restore the critical adjustment points on your NX 1x11 rear derailleur. The kit includes the B-adjust screw and limit screw hardware designed to match the original SRAM geometry so you get consistent chain-to-cassette clearance and end-stop accuracy. These small parts are precision made to SRAM tolerances and finished for corrosion resistance, keeping crucial indexing and B-screw settings stable ride after ride. Because the B-screw and limit screws determine cage angle and high/low stops, replacing worn or stripped fasteners can bring back crisp shifting without the cost of a full derailleur swap.

Key Features & Benefits

Designed as a direct-fit replacement for SRAM NX 1x11 derailleurs — no modification required. The kit restores both the B-screw adjustment that controls upper pulley-to-cog gap and the limit screw that defines the derailleur's high/low travel. Real-world benefits: • Restores accurate shifting after impact, corrosion, or stripped threads. • Precision-machined screws with a corrosion‑resistant finish for reliable long-term performance. • Small package and low weight — easy to carry as a field spare for trail repairs.

Fit, Compatibility & What’s Included

This kit is intended for SRAM NX 1x11 rear derailleurs and carries SRAM Model ID RD-SPP-A0. It replaces the factory B-adjust and limit screw components on SRAM NX 1x11 derailleurs; it may also be compatible with closely related SRAM 1x designs but always check fit against your specific derailleur model before install. Physical details: Shipping dimensions: 1.25" x 0.5" x 0.2"; weight: 0.1 lb. The small footprint makes it ideal as a spare in a saddle or frame pack. Typical installation requires common bike shop tools and basic mechanical knowledge — see our FAQs and sidebar tips for setup guidance.

Who This Kit Is For

If you ride a mountain bike equipped with a SRAM NX 1x11 drivetrain and you’ve experienced poor B-screw adjustment, stripped limit screws, or derailleur damage from crashes or corrosion, this kit is a low-cost fix to get you back on the trail. It's perfect for home mechanics, bike shop techs, and riders who carry essential spares on long rides. Ideal user: Mountain bikers who want a fast, reliable replacement for small but critical derailleur hardware — especially those who prefer repairing components rather than replacing the whole derailleur assembly.

Frequently Asked Questions

Will this kit fit any SRAM derailleur?

This kit is a direct replacement for SRAM NX 1x11 rear derailleurs (SRAM Model ID RD-SPP-A0). It may fit some closely related SRAM 1x derailleurs, but compatibility isn't guaranteed—check your derailleur's model ID or consult a mechanic before purchasing.

What tools do I need to install the B-adjust and limit screws?

Installation typically requires common bike tools such as a small screwdriver, hex key set, and a torque driver for final tightening. Exact tool size can vary by derailleur—bring both small Phillips/flat drivers and 2–3 mm hex keys when working on the hardware.

How can I tell if I need this kit?

Symptoms include inability to set correct B-screw gap, shifting that won't index at the top or bottom of the cassette, visible stripped screw heads, or wobble in end-stop adjustments. If the derailleur is otherwise functional, replacing these small parts often restores proper operation.

Is it better to replace the screws or the whole derailleur?

If the derailleur body, hanger alignment, and pulleys are in good condition, replacing the B-adjust and limit screws is a cost-effective repair. Replace the entire derailleur if the cage, hanger, or internal mechanisms are damaged or bent.

Does this kit come with a warranty?

Warranty coverage depends on SRAM's and Forest Bikes' policies. Parts sold as replacement hardware typically carry a limited warranty against manufacturer defects—retain your receipt and contact customer support for details on warranty claims and return procedures.

Can I carry this kit on trail for field repairs?

Yes — the kit is compact and lightweight (shipping dims 1.25" x 0.5" x 0.2", ~0.1 lb), making it an excellent addition to a saddlebag or multi-tool kit for remote trail repairs.

Buying Guide

When buying replacement derailleur hardware, confirm exact compatibility by matching the derailleur model ID or manufacturer part number. Small fasteners are cheap insurance: replacing a stripped B-screw or limit screw often restores shifting and avoids the expense of a full derailleur replacement. Carry a compact hardware kit on long rides if you frequent remote trails. Choose original-equipment parts like this SRAM kit for assured fit and function, and always keep basic tools to make quick adjustments or installs in the field.
