Normally, road racing bicycles have more trail than touring bikes but less than mountain bikes. Mountain bikes are designed with less-vertical head angles than road bikes so as to have greater trail and hence improved stability for descents. Touring bikes are built with small trail to allow the rider to control a bike weighed down with baggage.
Bike geometry parameters: wheelbase, steering axis angle, fork offset, and trail. Bicycle and motorcycle geometry is the collection of key measurements (lengths and angles) that define a particular bike configuration. Primary among these are wheelbase, steering axis angle, fork offset, and trail.
A Rohloff Speedhub hub gear A Shimano XT rear derailleur on a mountain bike A bicycle gearbox with chain tensioner. Bicycle gearing is the aspect of a bicycle drivetrain that determines the relation between the cadence, the rate at which the rider pedals, and the rate at which the drive wheel turns.
The numbers (45/45, 36/45, 36/36) refer to the angle on the cartridge bearing they use. All these bearings look similar. Campagnolo Standard: 45/45. (often referred as Campagnolo standard) This is common in BMX frames, BMX-derived dirt jump frames (like the Transition Trail-Or-Park). They are also common on road bikes.
For example, freeride bikes have steeper head tube angles and shorter wheelbases for low-speed stability on technical stunts, while downhill bikes have slacker headtube angles and longer wheelbases for absolute high-speed stability at the cost of low-speed maneuverability.
Camber thrust contributes to the ability of bikes to negotiate a turn with the same radius as automobiles but with a smaller steering angle. [1] When a bike is steered and leaned in the same direction, the camber angle of the front tire is greater than that of the rear and so can generate more camber thrust, all else being equal. [2]
A typical dirt jump-mountain bike. Dirt jumping uses a specific kind of bike. BMX, for instance, has a range of bikes built for this activity. One of its key differences from general purpose bikes is the fit. There is only one standard BMX dirt jumping bike frame, which is meant to fit all riders, young and old. [2]
The rider on a "free-tilting" and "passive-tilting" trike usually can apply a steer torque directly, which then controls the tilt angle indirectly, as on bicycles and motorcycles. The rider on a "free-to-caster" trike, on the other hand, can apply a roll torque directly, which then controls the steer angle indirectly.
