Product Details

Overview & Technology

SRAM's cassette lockring (Model ID: CS-SPP-A0, part #11.2415.013.000) secures the OG-1070 12T small cog to the cassette stack, keeping gear spacing and engagement precise. Built as a simple but critical interface between the cassette and freehub, this lockring is manufactured to SRAM's tolerances for reliable drivetrain performance. The lockring uses a precision-machined spline interface and a corrosion-resistant finish to resist galling and wear where the ring meets the cassette. At roughly 0.05 lb (≈23 g) and compact shipping dimensions, it's a lightweight replacement part designed for minimal weight penalty while delivering secure, repeatable clamping force.

Key Features

Materials and construction: machined lightweight alloy with an anodized surface finish for durability and low weight. The part is engineered for a snug spline fit to prevent micro-movement under pedaling load, helping preserve cassette indexing and shifting crispness. Real-world benefits include consistent cassette retention after repeated removals and installations, reduced risk of fretting between cassette and lockring, and compatibility with standard cassette lockring tools for quick roadside service.

Fit & Compatibility

This lockring is specified for the OG-1070 configuration and is tailored for the 12T small cog variant. It's compatible with SRAM cassettes that use the OG-1070 small-cog interface and fits standard road/MTB lockring spline tooling. Because lockring spline dimensions are standardized across most modern road and MTB cassettes, it will work interchangeably with many freehub bodies that accept SRAM's OG-1070 cassette series. If you're replacing an existing lockring, check the part number and the cog sizing on your cassette. This SKU complements other SRAM variants and part numbers (11.2418.002.000, 11.2415.027.010) listed for alternate lockring styles and fitments.

Who It's For

Mechanics, home wrenchers, and road cyclists who run SRAM OG-1070 cassettes with a 12T small cog will value this lockring as a direct replacement or spare. It's ideal for riders who frequently service drivetrains and need a reliable, OEM-spec lockring for repeat installations. If you race, commute, or tour on a SRAM-equipped road bike, keeping a fresh lockring in your spares kit prevents shifting issues caused by worn or cross-threaded rings and ensures secure cassette retention under hard efforts.

Frequently Asked Questions

What tool do I need to install or remove this lockring?

You need a standard cassette lockring tool that fits SRAM/ Shimano-style spline lockrings (Park Tool-style 12-point lockring tool). Use a torque wrench or appropriate spanner for consistent tightening.

Is this lockring compatible with Shimano cassettes or freehubs?

The spline interface follows common standards used by many cassette manufacturers, so it will often fit compatible Shimano-style freehubs. Always verify fit with your specific cassette model and freehub body before installation.

What torque should I use when installing the lockring?

Follow SRAM's cassette installation guidance when possible. If you don't have a spec available, tighten until the cassette stack is securely clamped and free of play, checking indexing. Using a torque wrench for repeatable results is recommended.

How do I know if the lockring needs replacing?

Replace the lockring if threads are damaged, splines are rounded from tool wear, or the ring no longer holds the cassette securely. A worn lockring can cause shifting problems and should be replaced to maintain drivetrain performance.

Are there different variants and how do I choose?

This SKU is for the OG-1070 12T small cog configuration. SRAM also offers variants (11.2418.002.000, 11.2415.027.010) for different cassette families—match the variant to your cassette model and cog size for correct fitment.

Buying Guide

When buying a cassette lockring, prioritize fit over aesthetics: confirm the lockring variant matches your cassette family (OG-1070) and cog size (12T small cog). Check part numbers and manufacturer notes to ensure compatibility with your freehub and cassette stack. Also consider materials and condition—machined alloy lockrings balance lightweight and durability for road use, while replacement is inexpensive compared to drivetrain wear. Keep a spare in your tool kit if you perform frequent cassette swaps or service.
