What tool is needed to remove this freewheel?
#1
Hello,

I was wondering if someone could recommend to me which removal tool is needed to remove this freewheel? I recently broke a couple spokes and the freewheel needs to be removed to access the hole to put a new spoke in. I put the ruler there to measure the diameter of the space, it's about 35mm-ish. I was looking at park tools freewheel recommendation site, but don't see one that would necessarily match. Would the FR-6 or FR-8 work? Thanks!

The bike in question is a Public Bikes V1. The Freewheel is Tri-Diamond and the hub is Shunfeng.

If it has no grooves other than two small holes across from each other, it is a basic freewheel and will probably require a destructive removal procedure and then replacement. Which sounds bad but your new one should be of better quality and will be built for future removal with the proper tool. (assuming you buy a nicer one built proper for tool removal. If the spanner does not work for you, use any method of destroying it till you can get it a vise or a plumber wrench to crack it off the hub. be very careful to not damage the threads on the hub. Your pics were not a hot link. Here is a link that may help you

Thanks. I am new to bike repair, but I do not think I require a destructive removal. There are 8 grooves. I was reading the specifics of Park Tools FR-6 and the measurements seem like they might work. It says "The FR-6 has four notches approximately 32mm across measured inside to inside and 40mm outside to outside". I have fixed the images:

Put the wheel in a vise, freewheel on top... Use a punch and a hammer to unscrew it

Thanks everyone for the replies. The vise/hammer/punch idea is a good one, I just don't have access to a vise right now. I took a risk and ordered the Park Tool FR-6. I got it today and it fits perfectly.

With a breaker bar and a 25mm socket, or a crescent wrench and a cheater bar, I can now get it off easily.

Great job... With the righht tool, you can reuse your freewheel if it's still good... Remember to put grease on the hub before puting the freewheel back, much easier next time to remove it!

Thanks guys. I just wanted to correct my statement about the 25mm socket. The 25mm socket does not fit. I got an official response from Park Tools clarifying:

"Our FR-6, and all our FR Specialty sockets fit a 1” socket/wrench.
Our FRW-1 Wrench is a one-inch socket and securely holds freewheel and lockring tools (FR-1 through FR-8 plus the BBT-5/FR-11) for removal and installation."
