How does fork rake affect bicycle handling?

How important is fork rake?

Simply put, fork offset, or fork rake, is the distance between the front axle and the steering axis – the imaginary line running straight through the midpoint of the steerer tube. … Higher trail means greater stability and lazier, slower steering.

What does increasing the rake do?

The smaller the rake angle, the less effort is required to turn the steering. Though, the motorcycle will be less stable in a straight line. Conversely, a larger rake angle requires more effort to turn but tends to make the motorcycle more stable at high speeds and helps maintain a straight course.

Does fork offset affect wheelbase?

A common one is the thought that a reduced offset fork will pull your front wheel towards you, significantly reducing the wheelbase length. In actuality, the change is negligible. In the case of a 29’er with a 65 degree head angle, going from a 51mm to a 44mm offset fork will reduce your wheelbase length by 5.78mm.

How does front center affect handling?

Front-Center affects the rider’s weight distribution and bike handling when climbing and descending. … A longer Front-Center increases steering stability when descending and keeps mountain bikers from going over the handlebars when the front wheel hits bumps or the fork compresses under braking.

How does bike geometry affect handling?

It’s affected by three factors: wheel size, head angle and fork offset. The slacker the head angle, the shorter the offset or the bigger the wheel size, the more trail. Generally speaking, the more trail, the more stable the steering.

How much difference does fork offset make?

Increasing fork offset reduces trail. Larger wheels increase trail. With a larger wheel (e.g., a 29” wheel) the axle is higher off the ground compared to a smaller wheel. If you draw a line through the steering axis to the ground, it intersects the ground farther forward of the axle, increasing trail.

What is aggressive bike geometry?

Aggressive geometry puts your upper body down lower for aerodynamics and the bikes tend to favor a more twitchy handling traits. Relaxed geometry has you sitting in a more upright position and the bike is setup to feel more stable at speed.

How can I make my bike more stable?

Generally though, if you move the front wheel forward by decreasing the HTA, the bike becomes more stable. Conversely, if you move the wheel forward by increasing the fork’s offset you make the bike less stable.
