¿CINTAS DE DYNEEMA O CORDINOS PARA LAS REUNIONES EN VÍA LARGA?

¿Qué utilizas para construir tus reuniones en vía larga? Aquí te damos nuestra opinion y que conviene utilizar en cada situación.

¿Sabías que cuando haces un nudo en una cinta de dyneema esta pierde hasta un cincuenta por ciento de su resistencia? 

Aun así muchas personas utilizan este material para construir las reuniones en vía larga. En varias pruebas realizadas por algunas de las marcas de escaladas líderes, como DMM o Black Diamond, se ha demostrado que una cinta de dyneema con un nudo puede romperse tan solo con la energía generada por una caída de factor 1 (si no sabes que es una caída de factor 1, te recomendamos que mires este video).

Desde nuestro punto de vista podemos utilizar cintas de dyneema o cordinos, siempre y cuando consideremos los anclajes sobre los cuales construimos la reunión y entendamos las limitaciones de cada material. Así por ejemplo, si vamos a confeccionar la reunión sobre dos chapas con parabolts, los cuales consideramos seguros y fiables, podemos utilizar una cinta de dyneema sin problema ya que las probabilidades de que alguno de estos puntos falle es muy baja o nula y por lo tanto los riesgos de generar un factor de caída susceptible de romper la cinta son muy bajos.

Sin embargo, si vamos a construir la reunión sobre material móvil (empotradores o tascones) o poco fiable como por ejemplo pitones o buriles, nuestra recomendación es siempre utilizar cordinos de 7 mm de diámetro como mínimo. El cordino presenta mayor dinamismo a la hora de trabajar con las fuerzas que puede generar una caída o la falla de uno de los puntos de anclaje y esto reduce la sobrecarga que se produciría sobre el o los puntos restantes. Además sería más resistente y tendríamos un menor riesgo de rotura del cordino.

Pros de las cintas de dyneema 

  • Material liviano y fácil de transportar
  • Velocidad a la hora de construir la reunión

Contras de las cintas de dyneema

  • Solo sobre anclajes fiables (parabolts en buen estado)
  • Difícil deshacer el nudo cuando se carga
  • Pierde resistencia cuando hacemos un nudo
  • Largo limitado (60 o 120 cm)
  • Material estático
  • Poca resistencia a la abrasión

Pros de los cordinos 

  • Se puede utilizar sobre cualquier tipo de anclaje.
  • Se puede regular el largo fácilmente 
  • Permite construir reuniones con múltiples puntos de manera más eficiente.
  • Material dinámico
  • Más resistente a la abrasión

Contras de los cordinos

  • Material más pesado y robusto


Para nosotros no existe una respuesta absoluta. Siempre evaluaremos las circunstancias y haremos uso del material que tenemos entendiendo sus limitaciones.  Sin duda los cordinos son más polivalentes a la hora de construir una reunion, podemos ajustar el largo y nos dará una mayor seguridad a la hora de montar reuniones sobre seguros móviles. Sin embargo si sabemos que vamos a escalar vías en las cuales las reuniones están completamente equipadas con parabolts y en buen estado, una cinta de dyneema de 120cm podría ser una opción correcta.

¡Excelente!

We had an amazing experience with Southclimb. Santi, our guide, was friendly, patient and clear throughout our three days together. He kept things moving at a pace that was ideal for our level of experience, and made sure we were able to cover all the things we were looking for help with. We’re looking forward to coming back in the future for the next steps in our climbing journey. Thanks again Santi!

Santi is the best climbing guide you can imagine. As a reference, we two are 6a-7a climbers, but we wanted a local guide to help maximize efficiency in a foreign area. He was highly recommended to us by a friend who Santi guided a few months back, and he was as wonderful as described. He takes his role as Guide seriously and comprehensively, from helping you plan ideas for areas to concentrate on, considerations of weather and season, logistics for where to stay and how to get there (he picked us up one day, and we met him in our car another), as well as making himself available to help with any other questions or needs for the trip as a whole (not just the climbing part). Our long chain of detailed texts show how dedicated and sincere he is in wanting to help plan the best trip possible for you. This was highly unique, unexpected, above and beyond, and much appreciated. Before you've even met, he treats you more like a friend coming to visit Spain than a client that he is just doing business with, and that warmth goes a long way and sets him apart from most any other guide I've experienced (i've had great guides in my life, so this just reinforces Santi's particularly special character). Like I really felt like we were friends, and still feel like we are, as he reaches out and keeps in touch still and I really appreciate that relationship. Humanity, sincerity, and kindness in business--what a crazy (wonderful) concept! As a climbing guide specifically: he is consummately professional, impressively knowledgable and safe, as well as comfortingly sensitive to your climbing abilities and needs, and tailors each day with climbs that are perfect for you--if you want to be comfortable or if you want a little/big challenge, if you want to experience highlights of an area by switching up crags in the same day. He knows the areas so well and of course knows how to choose the walls that are in the shade or in the sun for whatever time of day or season you are climbing. There is so much variety and fun for either multi or single pitch too. In addition, when we were all climbed out for the day, he took the opportunity to show us the beauty of the local areas, playing also a photographer and travel guide. He also went home to let us borrow his guide book to other areas that we were headed to later, and kept in touch to make sure the rest of our trip went smoothly. So nice! Here is a person who treats his job as a climbing guide and ambassador for the area with such deep consideration and earnestness, and who treats his role as a human being with exceptional kindness and faith. We are so grateful that he came into our lives as a climbing guide and as a friend. Thank you Santi for being you, and please everyone call him now for any guiding adventures (he travels to guide too!) Also, his rates are so fair and reasonable. And you will be so happy if he is available to take you on an adventure with him! Cheers!

I had an incredible experience climbing Naranjo de Bulnes/Picu Urriellu with Santi. From the very first emails, communication was quick, clear, professional, and helpful - he gave us detailed advice on routes, logistics, and even transport and accommodation options.

On the mountain, Santi was outstanding you could see his love for the mountains and watched him come alive! He explained everything very clearly. His knowledge of the area and his patience with us made the whole day very enjoyable.

We can't recommend him enough - if you're thinking of climbing in Picos de Europa or anywhere else, book with Santi. Thank you for helping us make this such a memorable trip!
