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.

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

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.

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

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

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.

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
