Bike Repair January 19, 2026Hello everyone, I have this lovely old Dura-Ace wheel, but it has this annoying very obsolete 6 speed freehub with the top cog that threads externally. Can I upgrade it to 7 speed freehub? You cannot fit a 10mm allen key inside, this is a weird different spline interface, anyone know which tool fit?
