Spinergy has been famous for using an alternative to stainless steel spokes for years. Their spoke is based upon a use of a special fiber. Specifically a spoke with “over 30,000 strands of polyphenylene bensobisoxazole fiber”. These fibers are then coated with a chemical, water, and UV resistant material which can be colored. The PBO spokes also have three times the strength of stainless steel, according to Spinergy, at half the weight of stainless steel spokes.
Okay, so PBO spokes, aluminum rims… how does that work? It actually works out really well. I think the common thought most folks might have is that if the spokes are not steel, then they must be flexy. Well, that just isn’t the case here.
