English to Spanish Other Sports / Fitness / Recreation Snowboarding

Hi:

I'm translating a snowboarding gear catalogue and here I'm dealing with the characteristics of these boards.

Do you know the meaning of "edge hold" or "edge-hold". I found out that Edge hold is used to describe a ski or snowboard performance characteristic. The term is used when describing the ability of a ski or snowboard to hold the arc of a turn on firm snow. So these are my tries:

- This is because of its reactive pop, precision and positive edge-hold. (La razón de ello es su pop reactivo, su precisión y equilibrio en giros positivo.)
- Outstanding edge hold comes from the camber under the bindings, while flat camber between delivers responsive fun. (El camber bajo las fijaciones favorece un equilibrio excepcional en los giros, al mismo tiempo que el camber plano de la parte central aporta una diversión receptiva.)

Do you a specific term for this in Spanish? I've found many terms that I find difficult to understand so if you know a good Spanish website about snowboarding I'll be very grateful.

Thank you so much
