I seem to recall reading that while preparing to go after the hour record, Francesco Moser experimented with disc wheels that had sliding weights that would be initially located near the hubs to allow for better acceleration, but would then be carried by centrifugal force toward the rims as he accelerated to top speed to assist in maintaining momentum. Is not the location of the weight significant, i.e. more weight concentrated in the rims being a hinderance with respect to acceleration but a help with respect to maintaining a relatively high speed?
