Unior 1670.9/4 Cassette Lockring Tool with 12 mm Guide-Pin — precision-engineered for modern thru-axle hubs and serious mechanics. Designed to remove and install cassette lockrings on hubs with 12 mm through-axles, this tool neatly bridges the gap between high-performance hubs and workshop-grade tooling.

Key Features:

  • Integrated 12 mm guide-pin ensures correct alignment with thru-axle hub systems, reducing wear and ensuring accurate engagement.

  • Compatible with cassette lockrings – purpose-built to fit the latest freehub designs and modern hubsets.

  • Durable, high-quality construction following Unior’s standards for longevity and reliable workshop performance.

  • Designed for professional or discerning home mechanics working on premium road, gravel or mountain bike builds.

  • Ergonomic and efficient: makes maintenance cleaner, faster and reduces risk of unintended damage to high-end wheel components.

  • 1/2" Socket

Why it’s a smart choice for serious cyclists and mechanics:
When you’re building or servicing top-tier bikes with modern hub standards (12 mm thru-axles included), generic lockring tools can mis-align, slip or even damage your components. This Unior tool is designed exactly for that scenario—making it ideal if you’re handling performance hubs, upgrading wheels or managing your bike build kit. With your aesthetic of premium gear that works as good as it looks, this tool fits seamlessly into the toolkit of cyclists who demand high-end functionality.

Usage context:
Whether you’re installing a new cassette on a lightweight wheelset for a race build, servicing your favourite gravel rig before a long ride, or simply maintaining gear at home with workshop-grade precision—this tool gives you the control and quality required. There's no compromise when it comes to supporting your high-end components.
