Great for the job

  • Familiarity:I've put it through the wringer

I didn't give it 5 stars because it just works, it doesn't do a complex task. It is worth noting that it fits on the XD driver body which is deeper, so that is nice for removing those, and any other shimano/sram cassette you have.


Does its job

  • Familiarity:I've used it several times

Pretty handy tool to have in the tool box. Works well and fits my SRAM 11 speed cassette perfectly.


not for 15mm centerlocks.

  • Familiarity:I've used it once or twice and have initial impressions

I bought this to switch out my rotors to the new freeza centerlocks and didn't realize until I went to install that you need a BB tool for centerlock rotors on a 15mm axle. other than that it worked great for the rear rotor and cassette.


Works as Described

  • Familiarity:I've put it through the wringer

If you have a Shimano or Sram cassette you need this tool.


Just one of those things.

    This is one of those tools you just need to own. Easy to use, durable, and comes in very handy.


    Gotta have it.

    • Familiarity:I've used it several times

    If you are going to change your Shimano or Sram cassette, you've got to have one of these. As usual, Park makes a very functional tool. I prefer the one with the centering pin(FR-5G)-just makes the job a little easier for 2 bucks more.


    Another essential for the tool box.

    • Familiarity:I've put it through the wringer

    Yep, you are going to need one of these too.

    Have you ever heard the term..' Up shit creek without a paddle? ' This is your paddle.


    crucial tool

    • Familiarity:I've put it through the wringer

    You never know when you'll need to swap a cassette, and when you aren't going light enough to warrant the stein hypercracker, this is a good second. Make sure your chain whip is on sturdy and you'll be set.


    Good tool to have in the toolbox

      I've used this twice already. Very glad to have this in the toolbox.


      Does the job

      • Familiarity:I've put it through the wringer

      This tool is precisely made, fits in to my park socket set to have a socket cassette tool, and has removed many a cassette.


      Good Tool

        Works great. need to use in conjunction with chain whip. model number FR-5G has the pin, FR-5 comes without. pin helps stabilize tool, both fit xx1.


        Spare change for maintenance.

        • Familiarity:I've put it through the wringer

        This is an inexpensive tool that you will need in order to maintain good care of the cassette of your bike. I ride a lot and once a month I like to give a good tune-up to my bikes, in order to do so, this tool is a most have. If you want to do all repair and maintenance to your bikes by yourself, you'll need this. Very reliable and great quality.


        finally have one!

          Now that I have my own I don't know how I lived with out it! Coupled with a chain whip and wrench you have all you need to swap out cassettes!


          Great Quality from Park Tool

            Great quality that you can expect from Park Tools


            Great tool

              Great tool to have so you can switch out your cogs, definitely going to need a wrench and chain whip to use with this tool.


              Must have

                Many years ago my local mechanic got sick of me coming in to get cassettes changed. So he sold me one of these. It has saved me so many trips to the bike shop that's for sure! Changing a cassette is something every cyclist should be able to do, and this tool is the best!

                So can this be used with other brands of...

                So can this be used with other brands of bottom brackets? I have a Truvativ sealed cartridge BB. Thanks!

                This tool is for a Shimano or Sram cassette-not for bottom brackets.


                It works

                  It works, it works well. I've had the same one for what, 7 years now? I've removed and installed a lot of cassettes in that time. In addition, it handles my centerlock disc rotors nicely as well. You're going to need a big honkin' wrench and a chain whip with it, be warned.
