After a long hiatus from biking I've decided to get my old Kuwahara road bike going again.

I wanted to re-grease the hubs, but after taking the wheel off and inspecting it. I realized that the much younger not so smart me, tried to take it off without the right tool and broke off one of the splines.

The problem is that's it's an old Suntour 3000 accu-shift 6 speed with the 4 notches.

If I get the right tool and it does come off would you reuse it?

Would anyone know of a cheap no hassle alternative freewheel?

Thanks for any advice.
