New for 2011/2012 Swix Marathon High Fluor Wax is a hard durable glide wax for long distance cross country racing. Developed especially for wet dirty contaminated. High Fluor content.
The hard consistency absorbs less dirt in wet conditions and works well in cold conditions.
BW additive is for reduced friction against dirt particles. The BW additive is also positive in cold conditons when there is partially dry friction.
