Abstract
Abstract A lever for hand operation of the brakes and clutch from the handlebars of a cycle, wherein said lever is of a configuration for avoiding engagement with the fingers of the hand when the brakes or clutch members are actuated by depressing of the lever against the handlebars. The lever is particularly designed and constructed for ease of use during actuation of the brakes or clutch, but provides a sufficient clearance between the lever itself and the forefinger of the hand in the depressed position of the lever for precluding pinching or squeezing of the finger against the handlebars, thus improving the operating efficiency of the cycle.
