In essence, organic products focus on the ingredients, while eco-friendly products focus on the entire product lifecycle. **

Organic farming practices can be more sustainable than conventional methods in terms of reducing chemical inputs, promoting biodiversity, and improving soil health. However, there are challenges to the scalability and efficiency of organic farming, which can impact its overall sustainability. For example, organic farming typically requires more land and labor to produce the same amount of food as conventional methods, which can limit its ability to meet global food demand. Additionally, the transportation and distribution of organic products can have a higher environmental impact due to their shorter shelf life and the need for refrigeration. Overall, while organic farming has many sustainable benefits, there are also limitations to its long-term sustainability on a large scale. **

It's important to consider factors such as rider weight, riding style, and the type of trails or terrain the bike will be used on when choosing the appropriate suspension setup for a full suspension bike. **
