Park Tool FR-5.2G Cassette Lockring Tool with Guide Pin ,Blue,5 mm

Only used it twice and worked flawlessly

An upgrade from my old school FR5 without the guide pin, I concluded that it's a lot less faff with a pin v reinstall the skewer, plus it is then practical to use a socket and torque wrench instead of a spanner. Works well and seems to be the usual good quality from Park Tool. Alas I then also then "required" an FR5 with a through axle sized pin too for my turbo trainer but you can never have too many tools in the man cave / lady lair so it's all good, right? The CA Proposition 65 notice on the packaging is a little unclear, does it apply to the materials of the socket itself or the plastic packaging?

Used this to swap the rear cassette on my Bossnut. Removed a knackered OEM one and fitted a Sunrace replacement. Perfect fit, absolutely rock solid and the guide rod is a handy addition. It's Park Tool so I expect it to last a lifetime.

After an accident on my bike I needed to replace a number of components, this was originally bought to allow me to replace the freehub on my rear wheel. It makes fitting and removal of the cassette very easy. You will need a 1" AF socket, to allow you to use a torque wrench. I Forgot not all the world is Metric, Americans still use imperial sizes. Subsequently have replaced the cassette and this ensures you can do it easily without damaging components.

Did the job

Exactly what I needed to fit my sram cassette and centre lock discs

Just what I expected , does the job correctly no problems.

A sturdy tool well designed for removing and fitting a bike cassette. Makes a job so much easier with the correct tool.

Very good quality as expected by park tool. Worked nicely

Muy buena herramienta, de marca especialista en herramientas para bici, buen precio, pronta entrega

Goede pasvorm met weinig speling op de tanden. Geschikt voor shimano en sram casettes. Lukt ook met sram xd casettes (12 speed) maar daar hebben ze een betere tool voor.

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.

Goede sleutel. Juist passend.
