Freewheel removal tool - noob mechanic alert
 

I've switched out chainrings on my singlespeed Cross Check to play around w my gearing, but I've never changed the rear cogs myself. My LBS did it the few times I switched.
I'm a little unclear on what tool(s) I need here--I've got 3 different cogs - 17, 18, and 19 T, and would like to be able to switch 'em out for different locales. They all look different though, different number of splines - pls see the pics. Is there one tool that'll handle all 3 of these, or do I need 3 different tools?

I have this one, the Park FR-6, and it should work for the first two:

The ACS has six slots and I think you need one of the ACS Crossfire tools:

So, no, I think you need two tools. 😊

Thanks!!!

Or just buy the park tool and shave off two prongs if you want to save a few dollars lol

So you joined the forum to post that? HAHAHAHAHA. Oy vey.

Folks don't shave your tools unless they are hairy and if your tools are hairy you should have taken better care of them. Use the correct tool for the job so you don't damage any components or ruin a good tool.

You're right, I should have added a disclaimer saying that what works for me may not work for others, good catch


I'm just a broke Med student paying tuition to work 40 hrs a week without pay. so yes saving a dollar here and there is vital. But my bad I should have mentioned that.


That being said, I modify what ever tools i have to get the job done. If it works, it works

Or get an ACS 8 notch that the FR6 will work on.


On another note, how do you all get the cheap crap single freewheels off that have no notches?

I know how I'm going to get it off but curious how else its done.

Also an SS noob but have a ton of C+V bikes, crap, etc, etc as well as kept my kids SS/fixie going through HS for him. ;)

Welcome - hope you enjoy your visits to this sub.

Thank god I've only had to deal with one of those cheap, not meant to be reusable freewheels once. I mostly followed a Park Tool helper video I found for "Destructive Freewheel Removal." Basically just break it apart to get it off. But I kept a close eye on the loose small parts and was careful with the ball bearings so it did get put back together to live another day with another person who was happy to be given it.

Have fun with yours...
