What does 99300 mean on my inno shaft?

Hey guys,

I have an inno 4000. It has 99300 printed on the shaft. Is this the flex? what does it mean? Thanks.

That would be a really stiff shaft

perhaps the model number.

99 is the dual concave shape( or round i forget)

300 is the flex (see flex chart, about 80)

i thought 99 just meant standard shaft?

[Buzz_LightBeer 974]

you may be right, my 4000 says 99260 on it and its a "5" shape, i also have a Klee 1100 thats "0" shape and says 99160

so 99300 means standard shaft, and a 300 flex? so roughly an easton 85?

Okay thanks Buz lightbeer I didnt see your post. Damn this shaft really feels like a 90-05 flex in easton.... it's quite stiff. Anyone know if this shaft will get whippier after use? Thanks.
