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. .Iadd.
