20110109060 | ACTIVE SHOCK-DAMPING SYSTEM - Bicycles and bicycle suspension systems including a sensor configured to sense a force or torque exerted by a rider on a bicycle, and a suspension adjustment mechanism configured to adjust a parameter of the bicycle suspension system in response. A controller or suspension management unit may be provided to receive data from the sensor, determine a corresponding suspension configuration, and transmit a suitable signal to the suspension adjustment mechanism. Accordingly, desired suspension characteristics may be achieved under various riding conditions. | 05-12-2011 |
20100220947 | BICYCLE BOTTOM BRACKET - An improved bicycle bottom bracket system and methods of manufacturing and installing such a system. The improved system generally includes bearings mounted within bearing cups on either side of the bottom bracket shell of a bicycle frame, and an alignment mechanism designed to result in substantially parallel, concentric alignment of the bearings. The alignment mechanism generally involves some form of aligned engagement of the left and right bearing cups with each other, such as direct abutment or threaded engagement. | 09-02-2010 |
