Hello,

I have an older diamondback hybrid bike with a shimano freewheel. The rear rim got bent and I found a new one for fairly cheap. I had a park tools FR-5 freewheel removal tool I had never used. It said it works with shimano. It looks like it would work, but when I try to put the tool in the freewheel, it just seems like it is juuuuust sliiightly too large. Is there a smaller shimano tool? This is the only tool I have, but a bike shop said all I needed was the shimano key to remove it.

I tried to use the tool on another freewheel, but I might have damaged it a little trying to get it into the initial freewheel too aggressively, so I'm not sure if it would have fit.

Thanks
