Why are the spokes of a bicycle crossed?

Bicycle spokes can be braided in many ways, including direct radial braided and tangential braided, namely radial and cross braided.

Radial weaving is the simplest and requires the shortest spokes, but vibrations from the ground are transmitted directly to the body and then to the rider’s PP.

There are many tangential weaving methods, which have longer spokes and are more complex than radial ones. Among them, the most mature and most commonly used is the three-crossed weaving method, in which the spokes start from the huagu to the wheel ring and have a total intersection with three spokes.

The benefits of tangential compilation are as follows:

1, have certain elasticity, can absorb part of the ground vibration, better comfort; More importantly, the power from the rear flower drum is transmitted to the wheel ring along the tangential direction, so the power transmission efficiency is higher. The tangency method has obvious advantages, so it has become the common method of bicycle wheel group.

2. The radial braided spokes have poor resistance to impact force from the side. If the side of the wheel ring is hit, the wheel ring will be easily deformed. With tangential weaving, spokes are staggered and overlapped so that when one of the spokes is hit by a side impact, the other absorbs part of the impact underneath, making the rim more resistant to side impact.
