Racing Sheet Pro is the outcome of the continued development efforts of FSE Robline®. Made of a mix of impregnated Dyneema® and XLF, the core provides even greater stability in the cleats and allows sailors to use Racing Sheet Pro even in its stripped state. The cover made out of a Polyamide/Dyneema® weave makes this sheet abrasion resistant and gives it good grip and excellent stretch performance.

Dyneema® core: lowest weight with the highest breaking strength
Polyethylene which is the raw material for Dyneema® is changed on a molecular basis and in addition is stretched in one direction. These stretched molecule chains increase the breaking strength and decrease the elongation. Therefore Dyneema® has the lowest stretch at break of all synthetic fibers. Dyneema® has a very low specific weight and is therefore buoyant. The only disadvantage is that it creeps more than some other raw materials.
This means the cover can easily be removed from the rope ends without reducing the breaking strength due it's fiber shows a permanent elongation under load. Dyneema® is used as core material in high-tech ropes. The core will carry the load whereas the cover is just used for abrasion and light protection. Therefore Dyneema® it has too a good abrasion resistance and resistance against sunlight.
