Unior Shimano / SRAM Cassette Lockring Tool with Guide Pin

This is Unior’s compact cassette lockring tool with an integrated guide pin, designed to stay seated in the lockring while you apply torque. It’s built for Shimano and SRAM HG-style cassettes and is especially useful when removing stubborn lockrings that like to push standard tools out. Key Functional Details Cassette lockring tool with built-in guide pin Guide pin threads into hub axle to prevent tool slip Compatible with Shimano and SRAM HG-style cassette lockrings Designed for use with 1/2" ratchet or adjustable wrench Compact steel construction Ideal for tight or over-torqued lockrings Compatibility & Technical Notes Compatible with Shimano and SRAM HG cassette lockrings Requires removal of quick release skewer before installation Use with chain whip (or equivalent) for cassette removal NOT compatible with Campagnolo cassettes NOT compatible with SRAM XD/XDR driver lockrings NOT for Centerlock rotors Manual hand tool — not designed for impact drivers Service / Ownership Context This tool is meant for drivetrain service when you want extra security against slipping. The guide pin keeps the splines fully engaged under load. Fit & Use Signals Good Fit: Home mechanics and shops servicing Shimano or SRAM HG cassettes, especially seized or factory-tight lockrings. Not A Fit: Campagnolo systems, SRAM XD/XDR cassettes, or riders looking for trailside tools. Same job as a normal HG cassette tool, but the guide pin is the whole reason to buy this. It threads into the axle after you remove the QR, which keeps the tool from popping out when you’re leaning on it. Huge help on seized lockrings. Biggest mistake: people forget to remove the skewer first, then wonder why it won’t seat. Still need a chain whip — this doesn’t replace that. Does NOT work on XD/XDR or Campy. Customers mix that up all the time. Great for home mechanics who don’t have three hands to hold tool + wrench + cassette. Failure points are user error: not threading guide pin fully, shallow spline engagement, or trying to impact it. Who this is really for: anyone who’s had a cassette tool slip under load. Who should avoid: Campagnolo users or XD/XDR riders. Mechanic advice: always fully seat the splines before torque. Light grease on lockring threads on reinstall saves future headaches.
