1 New stairs-use a spatula to apply sufficient compound to inside of nosing to eliminate any gaps between nosing and stair. 2  Apply appropriate R.C.A. 3  Stair Tread Adhesive to the step and balance of part being installed. 4  Let dry 10-15 minutes.
What does the tire tread do? On a normal, smooth road, the tread has only limited influence on the riding properties. The grip generated by the tire on the road is almost exclusively the result of the rubber compound. Unlike a car, a bicycle will not aquaplane. The contact area is much smaller and the contact pressure is much higher.
Directional (unidirectional) Directional tire tread features a large V-shaped pattern with large spaces or grooves between the tread blocks. The grooves improve hydroplaning resistance at high speeds by siphoning water more efficiently through the tread making these tires ideal for performance and ultra-high performance applications.
