Ridgerunner carbon fiber spreaderbars

Hi all,

I am planning to make some carbon fiber ones. I have ordered the ridgerunner but dont have it yet. Can anyone tell me the metric lengths of the spreaderbars? And what would be the sufficient diameter of the carbon bars be? Im thinking of outside 11,9 mm. / inside 9 mm.(Dont know in inches though.)

Thanks for the help and any comment is appreciated.

Cheers,
Frank


PS link to poles:

The RR aluminum spreader bars are as follows:

Diameter ~16 mm

Head end ~100 cm

Foot end ~72 cm

Weight - 280 gr including connectors and end caps. The connectors and caps are ~60 gr of this weight.

You will save something in the neighborhood of 100 gr.

Thanks for the information!
