My superstar Volta hubs have no spairs available and the freehub is slipping. You can’t feel it slip, but under power it makes lots of clicks and bangs.
Opening up shows the pawls are rounded. Could I give them a bit of a sharpen with the dremel, or is it sure fire death?
It should help, as per what others have said as long as you keep all pawls the same length. I would think it’ll be case hardened which might mean they don’t last so long even if you get the dremmeling spot on, but better than nothing if no spares are available.
