A mountain bike rider doing a trick on a pump track. A pump track is a purpose-built track for cycling.It has a circuit of rollers, [a] banked turns and features designed to be ridden completely by riders "pumping"—generating momentum by up and down body movements, instead of pedaling or pushing. [1]
The term is also applied to measurements used in design, construction and maintenance of track. Track geometry involves standards, speed limits and other regulations in the areas of track gauge, alignment, elevation, curvature and track surface. [2] [failed verification] Standards are usually separately expressed for horizontal and vertical ...
The Philly Pumptrack was created by Philadelphia cyclists Kenn Rymdeko, Heidi Grunwald, and Harlan Price. [2] Planning began when Rymdeko, who is now the project manager, was the president of the Philadelphia Mountain Bike Association. [3]
Aug. 23—SCHUYLER FALLS — The addition of a 950-foot pump track to Schuyler Falls' Jefferson Duquette Recreation Park is nearly complete, with a grand opening scheduled for Aug. 28. The asphalt ...
The Hallade method, devised by Frenchman Emile Hallade, is a method used in track geometry for surveying, designing and setting out curves in railway track. [1] It involves measuring the offset of a string line from the outside of a curve at the central point of a chord. In reality, string is too thick to provide a clear reading and breaks ...
The track bicycle made by Pinarello that Bradley Wiggins rode to break the hour record in June 2015. A track bicycle or track bike is a bicycle optimized for racing at a velodrome or outdoor track. Unlike road bicycles, the track bike is a fixed-gear bicycle; thus, it has only a single gear ratio and has neither a freewheel nor brakes.
The overall design pattern for the vertical geometry is typically a sequence of constant grade segments connected by vertical transition curves in which the local grade varies linearly with distance and in which the elevation therefore varies quadratically with distance. Here grade refers to the tangent of the angle of rise of the track.
