A lock ring tool is a basic tool that should be in your home bike kit. The FR-5.2G is well made & should last a lifetime of use, maybe 2. It constructed of a tough heat treated Tool steel w/12 splines for Shimano, Stan & SunRace cassettes & some dusk brake lock rings by Shimano. It has a diameter of approximately 23.4mm. The 5mm guide pin is designed for use on hollow quick release axils. The guide pin helps to stabilize the tool while your using it. This is really helpful when removing an old, stuck on or rusted cassette. The FR-5.2G can be used w/an adjustable wrench or a 1” (25.4mm) socket. A ratchet cannot connect directly to the FR-5.2G. I used the FR-5.2G when upgrading my Shimano 8sp cassette w/a SunRace 10sp cassette. I previously had been using a FR-5.2 (w/out pin guide) & really appreciate the pin guide. I know there are other cassette tools out there for less, but for something I’ll be using for regular maintenance like cleaning, I believe the little extra expense for Park Tool quality is worth it. Removing & cleaning your cassette is an often overlooked & forgotten bit of bike maintenance. It’s not difficult nor does it take very long to remove & clean your cassette periodically. This will definitely extend the life of not only your cassette but also the rest of your drivetrain. Thank you for taking the time to read my review. I hope it was helpful. Review: A Very Valuable Tool for DIY and Pros - Park Tools make some of the best bicycling tools available for pros as well as amateurs who like to tinker with their bikes. This one is no exception. Got it at a good price right before Thanksgiving. It was cheaper on the website but lack of shipping discount and duration for shipping made me buy here. Performed maintenance on all my bikes' and trainer's gruppos during winter without any hassle. Replaced one of the group sets with a new one too. Easy to remove and install the group sets with this and the "Park Tool SR-12.2 Sprocket Remover". Used my Wera torque wrench to install back the gruppos. Another thing going for Park Tools is the amazing instructions the folks provide on YouTube and the website. While blue is not my color, I will continue to support this American Enterprise. ## Features - This new updated FR-5.2G now fits the SRAM XX1 11-speed cassettes - Made in the USA. - International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Park Tool | | Color | Blue | | Finish Types | Natural | | Item Length | 9 inches | | Item Package Quantity | 1 | | Item Weight | 0.02 kg | | Material | Alloy Steel | | Material Type | Alloy Steel | | Measurement Standard | Metric | | Package Quantity | 1 | ## Product Details - **Brand:** Park Tool - **Color:** Blue - **Item Length:** 9 Inches - **Item Weight:** 0.02 Kilograms - **Material:** Alloy Steel ## Images ![Park Tool FR-5.2G Cassette Lockring Tool with Guide Pin,Blue,5 mm | Lockrings - Image 1](https://m.media-amazon.com/images/I/71Fo1DeuraL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ If You Care About Your Cassette, GET IT!! *by S***E on March 25, 2020* The Park Tool FR- 5.2G Cassette Lockring Tool is a professional grade tool.
