Strongest spokes on the market! The spokes are made from stainless steel and are produced exclusivly from Haan Wheels. You can see this on the head of the spokes where you can find the mark H. Due to the fact that the spokes are made of stainless steel you can be sure that they stay nice and shiny in all conditions. Haan wheels use steel nipples to prevent spokes from coming loose when riding like you would have with alloy nipples. These nipples have a special coating to prevent corrosion.
