These Victoire Cycles Splined Hubs remind me of Miche slot on sprocket, I just hope they perform a bit better. One thing I have noticed about anything spline drive on a fixed gear bike whether it be a crank or sprocket is that is is not long before you will feel some sort of play due to wear. I am interested to see if these hubs are any different, they look damn good and the sprockets look sweet too. Unlike the Miche sprocket it is the actual hub that is splined, could this solve the problem? They look pretty tough to me.
