Do skilled cyclists really "use the front brake alone probably 95% of the time"?
Reference - Cyclecraft by John Franklin


  A cycle takes more than twice as far to stop using only the rear brake compared to using only the front brake, which will usually stop the machine just as quickly as using both brakes. Nevertheless, you should always apply the rear brake, and slightly in advance of the front brake, so that a slight skid at the rear will warn you if you get close to the hazard point at which the bike may tip.
