Park Tool FR-5.2 Cassette Lockring Tool, Metal

I have an IHG but the disc brake rotor had somehow come loose. My existing spline tool has a guide which would require the axle to be removed but this is a bigger job than tightening the rotor. This tool does the job the hole is 12mm so it fits easily over the axle allowing me to tighten the rotor without any unnecessary work.

Park Tools are the best I’ve used. They fit perfectly and don’t wear out.A bit dearer than the cheap Chinese rubbish but I’ve found as a mechanic. “ The right tool from the right company buy wise buy once.

Removed my Shimano Ultegra 10 speed cassette with no issues, used it to put the new one on… no issues. Does what it says on the tin. Works with Tacx Neo 2 no problem.

All good not much to comment on its does what it needs to do.

Unfortunately this was incredibly poor build quality and broke on first use. Admittedly the bike was old the the but was very tight, but didn’t expect it to fall apart. Buy a more expensive one, It is worth it.

Much better quality than the ones included in cheaper tool kits.

Good quality and fit for purpose. Used to remove my old sram cassette and install new sram cassette. Seems expensive for what it is, but only need to buy it once and this ones certainly solid, should last forever. Worth the money given that some other types of these locks appear to be either a bit less robust, and believe me it did take some welly to get old lock ring off!, or more expensive. NB some have guide pins, not really necessary as you can screw the bikes quick release spindle nut down above this one to keep it square while using the spanner.

Worked perfectly to remove my shimano cassette.
