Park Tool Unisex Qkfr52gt Workshop, Black, One Size UK

Awesome piece of kit, great for thru axels and keeps the tool steady on the spline

Park Tools are reassuringly expensive, they just work. I’ve a number of other tools for cassette lock rings, but they always struggled with my SRAM 12sp cassette. The 12mm centre pin on this one did the trick as it ensures the tool is well seated, giving better purchase on the lock ring. Works fab across the various road, MTB and gravel bikes I have with Shimano and SRAM cassettes.

Absolutely bloody fantastic tool. That little blue extension really makes the home bike mechanics life FAR easier to remove a cassette!

This is a nice piece of kit works very well, but doesn’t fit Shimano Integra 11 speed cassette on my Canyon as the pin is too thick. Had to buy a second one with a thinner pin. Would be nice if you could remove the pin or if it came with two sizes. Maybe I didn’t read the compatibility so I’ve given it four stars because it’s very nice piece of kit

I stripped the end millimetre of the knurls off my old FR-5 Park Tool tool. It predates thru axles by 20 years and consequently unless the axle is removed there is only a small section of the tool that engages with the splines in the cassette. I had removed, replaced and tightened the 11 speed Shimano cassette without realising that I'd omitted to include one of the spacers. This meant the tool had even less to engage on, and what little there was stripped as I tried to remove the cassette. The new one arrived quickly and it is purpose built for the job. The removable blue centre guide (It is secured by a small hex bolt) fits perfectly into the thru-axle and the tool engages fully with the cassette's splines; thus the task of loosening and tightening the cassette is easy to do. A modest price to pay for such an essential maintenance tool.

Top notch tool as usual from Park tools.

Perfect for removing Shimano disc brake lockrings and cassettes. As always, it is a high-quality product from Park Tool. The guide pin is a great feature as it keeps the tool perfectly aligned and prevents it from slipping. Definitely recommended for any home mechanic.

This tool is perfect for the job. The central locating pin is precision made so the whole thing sits nicely within the rear cassette lockring, also this tool removes the brake disc 'internal' lockring.
