Libre Arminator
This is simply the best roller spreader bar available today. Have you had problems with your roller spreader? The strop falls out when you loose tension? Your strop moves awkwardly when the kite is at 90 degrees to you ? Not with the Arminator:

Features:
There is a flexible wire which keeps the strop in place all the time. It can turn 360 degrees one way and 180 degrees the other - so the strop moves smoothly on the roller at all times
Quailty stainless steell finish.

Adopted by most of the top racers across Europe - just shows how good it is.
