A brake operating device ( ) is configured such that actuation of the brake lever ( ) around the lever pivot ( ) displaces the cable ( ) in a direction transverse to the cable length toward the lever pivot ( ), as the user is actuating the brake lever ( ). This provides at least a 33% increase in mechanical advantage over the actuation range of the brake lever ( ).

Brake actuating system

A gear indicator for a bicycle that includes first and second control cables connected to first and second shift actuators, respectively. The gear indicator includes a housing mounted onto the control cables. The housing is spaced apart from the shift actuators and is not attached to the handlebars. First and second pulleys are disposed in the housing and are rotatable by a displacement of the first and second control cables, respectively. First and second gear display elements are movable in response to the rotation of the first and second pulleys. The first and second display elements indicate the currently selected gears of the bicycle.

Floating bicycle gear indicator

An elongated rotatable handgrip for use in actuating mechanisms on handlebar-steered vehicles that is readily engaged from an outboard hand position on the handlebar. The rotatable handgrip is mounted coaxially over the handlebar inboard of a stationary grip, having a length that is greater than that of the stationary grip, and is formed of a deformable material to improve torque transmission.

Elongated rotatable handgrip

Nubbed grips for hand-rotatable bicycle gear shifters have longitudinally elongated groups of nubs (50) that are angularly spaced apart by valley regions (44). Preferably, the elastomeric nubs are formed both on a cylindrical portion and an adjacent flanged portion of the grip.

Nubbed grip for rotatable bicycle gear shifter

A rotatable gripping surface for a derailleur-type bicycle gear shifting system is formed of a resilient material with axially extending alternating ribs and grooves. The ribs and grooves are spaced such that they fit naturally into the crooks of the rider's thumb and finger or fingers and the portion of the palm therebetween. The ribs provide an increased diameter to aid in the transmission of torque and to protrude above any mud which may have collected thereon. To further enhance the torque transmitting capabilities of the grip and the ability to remain effective in the presence of mud and other debris, the surfaces of the ribs are provided with a pattern of nubs. The hubs are engaged and deflected slightly by an operator's thumb and finger and the portion of the palm therebetween to transmit torque to the rotational grip. The deflection of the hubs as in the case of the ribs will provide for the transmission of torque in the presence of any debris such as mud which may be deposited on or between the nubs and the ribs and grooves.

Rotatable grip for derailleur type bicycle gear shifting system

Nubbed grips for hand-rotatable bicycle gear shifters have longitudinally elongated groups of nubs (50, 96, 142) that are angularly spaced apart by valley regions (44, 98, 156). Preferably, the elastomeric nubs are formed both on a cylindrical portion and an adjacent flanged portion of the grip. In an alternative embodiment, shark tooth nubs (142) offer leading faces (158) against which a hand of a rider may abut in either rotational direction for maximum torque transmission.
