I have a set of used Sram S60 carbon wheels running with a Sram 9/10s freehub. Currently they’re on my 10s road bike but I’m wondering what I’d heave to do to enable me to fit an 11s cassette on and use with my Cervelo S5. It definitely is a short free hub body so not a spacer issue. I’m just loathed to remove the free hub before I have found another one that I can replace it with. Compatibility issues? Anyone been there and done it?
