I have a pair of Fulcrum Racing 1 wheels (from about 2010) currently running 10 speed Shimano. To upgrade to an 11 speed do I only have to install an 11 speed freehub or are there other obstacles?
OP is suggesting replacing the freehub.Nope. The Racing 1 of that era use the Shimano CS-6700 freehub.
Don't confuse the fact that Fulcrum is a Campy product with the freehub that is on this wheel. It is Shimano compatible, not Campy compatible.Fulcrum = Campy. And since they have been 11-spd compatible since 1999 I would have thought that there was space for an 11-spd freehub and that OP is probably correct. No personal knowledge though.
I'm aware of that. I thought my post (since I linked to a Shimano freehub), would have made it obvious.Don't confuse the fact that Fulcrum is a Campy product with the freehub that is on this wheel. It is Shimano compatible, not Campy compatible.
