Good argument for designing disc rotors that can't chop off fingers for use in road racing (if ever UCI approved). Just lighten the solid disk with a number of slots or drillium rather than having spokes. There may be interest from the general public too. I'm not that comfortable with having a potential "finger guillotine" on my front wheel. Maybe a better idea is disc guards. This should fix both the problems of rotor burn and losing fingers. But I'm probably being too practical now.cobba wrote:There's plenty of nasty photos around of severed fingers from disc brake rotors.
