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.
Without a doubt, there is a lot to like about the Cantu Rova wheelset. The weight is competitive, at 1567 grams for our set. While it’s true there are lighter options available, most aren’t using 35mm section, 30mm wide external/24mm internal width rims.
