Road racing bicycle forks have an offset of 40–50 mm (1.6–2.0 in). [7] The offset may be implemented by curving the forks, adding a perpendicular tab at their lower ends, offsetting the fork blade sockets of the fork crown ahead of the steerer, or by mounting the forks into the crown at an angle to the steer tube.
The front wheel will usually also steer to that side. In a lean, gravity provides this force. The dynamics of a moving bike are more complicated, however, and other factors can contribute to or detract from this effect. [1] Trail is a function of head angle, fork offset or rake, and wheel size. Their relationship can be described by this ...
A bicycle fork is the part of a bicycle that holds the front wheel. A fork typically consists of two blades which are joined at the top by a fork crown. The crown is often at the front. Most suspension forks have an arch connecting the two side of the lowers (the part connected to the axle.)
Jones Counter on the front wheel of a bicycle. To measure road-race courses, the counter is fitted to a bicycle between the left fork leg and the front wheel. [5] The tab or tabs on the large ring gear engage with the spokes, thus providing drive to a Veeder-Root counter.
A true track fork, unless aerodynamics are the primary consideration, has round-section blades for greater lateral stiffness when sprinting. The crown is sometimes drilled to give the option of mounting a front brake when the bike is used on the road.
Wheels with Asanti 28 in (710 mm) rims on a police Hummer H2 car. The wheel size is the size designation of a wheel given by its diameter, width, and offset. The diameter of the wheel is the diameter of the cylindrical surface on which the tire bead rides. The width is the inside distance between the bead seat faces.
A fork end, [1] fork-end, [1] or forkend [2] is a slot in a bicycle frame or bicycle fork where the axle of a bicycle wheel is attached. A dropout is a type of fork end [3] that allows the rear wheel to be removed without first derailing the chain. Track bicycle frames have track fork ends, on which the opening faces rearwards. Because they do ...
Front suspension of a race car — the caster angle is formed by the line between upper and lower ball joint An example of a chopper with a raked fork at an extreme caster angle The caster angle [ 1 ] or castor angle [ 2 ] is the angular displacement of the steering axis from the vertical axis of a steered wheel in a car , motorcycle ...
