Saving 200 grams per wheel .... "PolyLight spokes significantly improve the damping of road vibrations, which makes for a noticeably smoother ride and reduces rider fatigue. Now you can rider faster and farther!"
Berd polyethylene spokes sound good.
Do they need streamlining?
From 'April Bicycle Retailer' ...
You may remember some fiber spokes a few decades ago that had great promise .... but would shatter from a hard sideways blow ..... hopefully these have passes some impact, abrasion, and cutting tests.
The literature on the website states: "PolyLight spokes are significantly lighter than the lightest high-end spokes available. Despite their incredibly low weight, PolyLight spokes are also extremely strong. In fact, they are stronger than most spokes on the market today."
and "Strength and weight are not everything. PolyLight Spokes are also designed to take anything you can throw at them. They are impervious to UV exposure and moisture and resistant to general wear and tear and impact."
