Flex question

[StroupSkier]

In the recommended ski thread, as well as several others, the stiffness of skis is rated between 200 and 300.

I tried to search, but after scanning the first 200 threads of 500 that popped up I could not find out what this number exactly meant.

Does anyone know if there are any units to it or how it is measured?

Stroup-

I'm pretty sure that's the Igneous flex index.

[pechelman]

right, its iggie flex
but where does that number come from is what I think he's asking

ie is it some sort of dimensionless number or actually representative of a spring rate lb/in

Yea, I tried doing a search of the Iggy flex and only this thread and 2 others came back.

I was trying to quantify the number in some way, like a spring constant.
