![]() ![]() The smaller the fork offset (the straighter the fork) the longer the trail - contrary to a wide-spread conviction. It depends on the manufacturer's type of making. No worries, even if you are between two sizes. This means that both the larger and smaller road bike frame size or mountain bike frame size recommended will be suitable. Negative values: hub follows the steering axis (fork "bent backward"). Built with a lightweight and durable Alutech frame with modern geometry for a more comfortable leisure ride, the Premier 4 is a reliable companion for the day-. Sometimes our bike sizing calculator will recommend two different bike frame sizing options. Welcome to the world's biggest open database of bike geometry. Positive values: hub preceeds the steering axis (as shown in the image). Compare different bikes and sizes side-by-side. Here defined as the angle between the floor behind the front wheel and the steering axis (see image above).ĭistance between the contact point (center of the contact patch) of the front wheel on the floor and the point where the "virtually" elongated steering axis meets the ground. TopOfPage | SteeringGeometr圜alculator | WheelDiameterTable | Text | Formulae Trail passes zero (turns to negative values) if the steering is turned by The comma as well as the point may be used as decimal point.įurther results from the above steering geometry data: Even if you failed geometry in high school, dont worry this crucial mountain bike geometry is not difficult and when done methodically you can easily use a. The cockpit fit measurements can be found by clicking on the Include Cockpit Fit Measurements at the bottom of the geometry table, which is on by default. The input field of the variable to be calculated must be empty. Enter the frame and cockpit measurements and the calculator will calculate RAD to the 1/100th of a millimeter.

Mountain bikes are designed for all types of terrain, from flat gravel paths to steep rocky trails. Geometrical Relation between Head Tube Angle, Trail and Fork Offset We have used the Higher Order calculator (HOC) given in Kernighan and Ritchie book as a model. ![]()
