Why are BMX parts so strong but so cheap (compared to mountain bikes)?

What are the challenges of manufacturing parts (droppers) that are suitable for various rider weights?

Are there any weight restrictions for your products?

I noticed this in the instructions for adjusting the column stroke, "Reducing the column stroke will also increase the bushing overlap and the length of the positioning pin, which is very useful for heavier riders." Should riders over a certain weight choose less The dropper stroke to extend the life of the column?

Are there any weight restrictions for your products?

What are the challenges of building a fork with a wide range of weights?

Suppose the rider's weight is 250, 300, or 400 pounds. How can they expect their fork performance?

What challenges do you face when trying to build a product that fits all rider weights?

Are there any weight restrictions for your products?

How does the suspension behave differently for very light riders, ideal weight (if any), and heavy riders?

Setting the bike to factory specifications at my weight brought me very close to maximum pressure. Coming from the completely rigid BMX world makes me want something harder, so I often get close to the limit. I think this is why I have so many suspension failures?
