A bicycle comprising a frame; a handlebar assembly attached to an upper steering tube of the frame in such a way that at least the relative rotation between the two with respect to an upper axis is allowed, but the relative displacements between both in the directions perpendicular to the upper axis are restricted; a fork attached to a lower steering tube of the frame so that it has the same degrees of freedom relative to the lower axis between the fork and the lower steering tube as the degrees of freedom relative to the upper axis between the handlebar assembly and the upper steering tube; and a means for rotation transmission for transmitting at least partially a rotation of the handlebar assembly with respect to the upper tube into a rotation of the fork with respect to the lower steering tube.

A tilt-decoupled steering device of a motorbike includes a handlebar bridge for receiving a motorbike handlebar, a fork bridge for receiving a fork leg, and at least one decoupling device connecting the handlebar bridge to the fork bridge. The handlebar bridge is mounted such that it can rotate about a steering axis and is secured about a tilt axis orthogonal to the steering axis, and the fork bridge is mounted such that it can rotate about the steering axis and about the tilt axis. The decoupling device transfers a steering movement and a steering torque in a steering direction about the steering axis between the handlebar bridge and the fork bridge, and compensates for a tilting movement in a tilting direction about the tilt axis of the fork bridge relative to the handlebar bridge.

A bicycle handlebar stem or stem/handlebar assembly has an inclined linear travel approximately 45 degrees from horizontal. This inclined path mimics a rider's natural arm inclination and pitching moment. 45 degrees is nearly ideal for most dropped bar road bicycles but different style bicycles may have an ideal angle between 30 and 60 degrees.

A method includes recording data about an advertising campaign; converting the data about advertising campaigns into ad time slot data including a time range in which a broadcast program runs and average number of times the advertisements run during the time range; and selectively generating an output visually indicating cost of advertisements versus time of day, number of intakes versus time of day, and cost of the advertisements versus time of day. Other systems and methods are provided.

A bicycle includes a frame, a suspension assembly and a steering assembly. The frame includes a head tube that rotatably receives a front fork assembly. A steerer tube extends axially away from a fork crown of the front fork assembly. The suspension assembly includes an upper tubular support longitudinally slidable relative to a lower tubular support. The upper and lower supports receive a first positive biasing means and a first negative biasing means. The lower and upper supports are respectively connected to the steerer tube and a stem of the steering assembly such that the upper support slides longitudinally relative to the lower support adjacent the stem and above the fork crown.

The present invention is in connection with the field of the cycling industry, and in particular it refers to a front suspension system of a bicycle, of the single-stem type, thus adapted to be arranged inside the steering head tube and specially conceived, thanks to its compactness, to equip road “racing” bikes but not exclusively intended for this category of bicycles.
