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

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.

Did the job

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

Used to swap my gears on to a replacement wheel Never done this before but it was painless Just YouTubed how to do it bought the tool and did it

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

Five stars. Well made tool for removal of rear cassettes. Mine was rattling like hell, so bought this to tighten it up - I'll change it out later this month. The rod goes down the hole for the axel so it will not slip out and damage the free wheel. Really happy.

It just works, using with a torque wrench etc just provides a nice tight fit for the cassette etc. Used with a socket of the appropriate size, only thing that could have been improved would be some sort of locking or magnetic mechanism to stop it randomly falling out of the socket. Other than that a good tool to have in your tool collection for home bike maintenance.

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.
