The hardness of skateboard wheels is typically measured on the durometer scale, with the most common ratings being 99a, 100a, and 101a. The higher the number, the harder the wheels. 101a wheels are the hardest, providing less grip but more speed, while 99a wheels are softer and provide more grip but less speed. 100a wheels fall in between, offering a balance of grip and speed. The choice of hardness depends on the type of skating and personal preference. **

The durometer hardness of skateboard wheels is typically measured on the A scale. The most common durometer hardness for skateboard wheels is 99a, which provides a good balance of grip and slide. However, skateboard wheels are also available in 100a and 101a durometer hardness for different preferences in riding style and terrain. **

The difference in rolling between 100a and 101a in skateboards is generally considered to be significant. The "a" rating refers to the hardness of the skateboard wheels, with 100a being softer and 101a being harder. Harder wheels (101a) typically roll faster and have less grip, making them better for smooth surfaces and technical tricks. Softer wheels (100a) provide more grip and shock absorption, making them better for rough surfaces and cruising. Therefore, the difference in rolling between the two hardness levels can have a noticeable impact on the performance and feel of the skateboard. **

The wheels with 101a are harder than the ones with 99a. The durometer rating measures the hardness of the wheels, and a higher number indicates a harder wheel. Therefore, the wheels with a 101a durometer rating will be more suitable for smooth surfaces and provide faster speed, while the 99a wheels will offer more grip and control on rougher terrain. **

The hardness of Spitfire Formula 4 skateboard wheels is typically 99a. This hardness level provides a good balance between grip and slideability, making them versatile for various skateboarding styles and terrains. The 101a hardness is slightly harder and may be more suitable for smooth surfaces or advanced skaters looking for a faster ride with less grip. **

Eco-friendly women may choose not to shave for a variety of reasons related to sustainability and environmental impact. Shaving requires the use of disposable razors, which contribute to plastic waste in landfills. Additionally, the production and transportation of shaving products can have a significant carbon footprint. By opting not to shave, eco-friendly women can reduce their personal contribution to waste and carbon emissions, aligning with their values of environmental conservation. **
