Park Tool FR-5.2G Cassette Lockring Tool with Guide Pin

When the chain sagged while coasting on my 2006 Co-Motion tandem, I need a tool to remove and service the Shimano freewheel. This lockring tool combined with a chain whip made the job easy. It dropped right down into the splines of the freehub smoothly thanks to both the guide pin keeping things straight and the splines of the tool matching so well to the splines of the hub. No slip or wiggle, very solid while turning, got that hub right off, cleaned up, re-lubed and we are back on the road.

A compliment tool to the cassette pliers I purchased. Bike maintenance is easy with this tool. Other options are available - this one worked for me.

Not much to get excited about but it is what you would expect from Park Tool, the guide pin is a nice touch.

Recommend the long shank version which helps center the socket in the axle

There are two versions of this tool, one with the guide pin and one without. I was recommended the version with the guide pin by some friends, and definitely agree that it's worth the small upcharge. Easy to align and stays secure.

Great design. I had the old one without the guide pin and it didn't stay in place like this new version. It works much better comparing with the old one without pin.

I used this tool to remove and install cassettes on both my road and mountain bikes. I like the guide pin because it helps in making sure attachment to lockring is correct. This tool is a must for the home mechanic - the ability to remove cassettes is necessary for proper cleaning and maintenance

Great tool

If you change the cassette/cogs yourself this tool is a must. Works well with any wrench.

A must have for swapping your cassettes. You'll need a 26mm socket if your going to use a torque wrench when tightening your cassette.

Good price and quality. A must have tool.

I have both styles. This one with the guide is the only way to go. Easy one person job.

It works as described. I was using it for a SRAM rear cassette and the fit was good, not too much play.

It aligns and seats well. It is better than the old one I can't find without the pin. It's been effective on expensive and very, very cheap cassettes. It's machined well, but won't blow you away. For that I'm still not going call it a an awesome value.

Can't perform the procedure without this tool, which pays for itself with the very first use. Seems durable enough for years of use in the future, even if used at a pro shop.

You will need this tool to install your cassettes. The updated version with the guide pin makes the tool foolproof. Improvement on an already great design. Made in the USA too! Whats no to like!

Exactly as stated.

Park Tools always work and I have not had any problems. The right tools always make the job easier

If you are serious about cycling, you need this tool as it is the only way to remove a cassette from your wheel. Don't pay a shop to do this simple task for you, get this cassette tool, and a chain whip and you are all set!

This tool, is well made and does what it was made to do! the guide pin makes it a no brainer... Ray Charles could have used this tool!
