Wheels

Wheels are the most stressed parts.

- Directly determinates the properties of whole bicycle and infuences cyclist´s efficiency.

- The most difficult is the transmission of tractive power from the hub to the rim.

- This ability is influenced the most by durability(stronghold) of spokes, surface of  heads and nipples.

- Differences in the transmission of tensile power are extensive, in the interval 3-8%.

- Is possible to achieve the best results with Aluminium spokes because their strenght is about 4000 N and  have large seating area.

- Stainless steel spokes have higher weight, their strenght is only 3000N and critical point is head bending.

- Reduced stainless steel spokes have lower weight but also expressively lower strenght, small transmission surface and greatly elasticity.

- Balance of all properties, as is mainly the weight of rim, strenght of spokes and settling in hubs are deciding factors for top wheells.
