The lever is rotatable about a brake axis to actuate the brake control mechanism and rotatable about a shift axis to actuate the shift control mechanism in the cable-release direction and in the cable-pull direction. The bicycle control device is configured to not displace the shift control mechanism upon actuation of the brake control mechanism. | 04-08-2010 |
20100081531 | Multi-Speed Sprocket Asssembly - A multi-speed sprocket assembly configured to receive a bicycle chain including a plurality of pairs of inner link plates, a plurality of pairs of outer link plates and plurality of rollers connecting the pairs of inner and outer link plates. The multi-speed sprocket assembly generally includes a smaller diameter sprocket and a larger diameter sprocket rotated about a rotation axis in a driving direction. The smaller and larger diameter sprockets include first and second pluralities of teeth spaced about their peripheries, respectively. The larger diameter sprocket has an inboard side including first and second projections axially extending therefrom. The second projection is disposed circumferentially aft, opposite the driving direction, and radially outwardly of the first projection. The first and second projections simultaneously support one outer link plate as the bicycle chain shifts from the smaller diameter sprocket to the larger diameter sprocket. | 04-01-2010 |
20090205330 | Master Cylinder Assembly for a Hydraulic Actuation System for a Handlebar-Steered Vehicle - A master cylinder assembly for a hydraulic actuation system for a handlebar-steered vehicle including a fluid cavity having an adjustable length. The master cylinder assembly generally includes a housing, a piston assembly, an actuator and an adjuster. The housing is mountable to a frame member and includes a chamber having a fluid cavity with first and second regions. The first region is in fluid communication with the hydraulic actuation system. The piston assembly includes a piston slidably disposed within the fluid cavity. The actuator is operatively connected to the housing and operatively connected to the piston to slidably displace the piston between an open fluid circuit position permitting fluid flow between the first and second regions and a closed fluid circuit position blocking fluid flow between the first and second regions. The adjuster is operatively connected to the housing to adjust a length of the fluid cavity. | 08-20-2009 |
