The javelin is primarily designed for tailwind throws. The NXB - Next Generation Blunt tip is made for maximum lift in predominantly tailwind and still conditions. The NXB tip is therefore thicker and possesses more of a blunt presentation than any other javelin tip on the market. This helps to create maximum lift and therefore longer glide during perfect wind conditions for this particular tip.

Advance Tip Control
What is Advance Tip Control, it is our way to optimise moment of inertia of the javelin. The new ATC technology makes the javelin correct it self directly to the path you have thrown it in and the javelin will have less tendency to change direction while in flight. It stays on the path you have thrown it. The other biggest benefit is, that you will feel what direction and path the javelin will go already in the run-up.

Requires good capacity both technically and physically with the thrower.
