## Description

desertcart.com : Park Tool FR-5.2G Cassette Lockring Tool with Guide Pin,Blue,5 mm : Sports & Outdoors

Review: If You Care About Your Cassette, GET IT!! - The Park Tool FR- 5.2G Cassette Lockring Tool is a professional grade tool. 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.
