Este avance marca un salto significativo desde las 12 velocidades actuales.<\/p>\n<h3>Detalles del prototipo<\/h3>\n<p>El cambio m\u00e1s notable es el cassette de 13 coronas. Aunque no se ha confirmado el escalonado definitivo, se especula con la inclusi\u00f3n de una corona de 10 dientes. Esto podr\u00eda estar relacionado con un nuevo n\u00facleo espec\u00edfico que se hab\u00eda filtrado previamente.<\/p>\n<p>Las <strong>manetas<\/strong> han sido revisadas, incluyendo un nuevo pulsador lateral accesible con el pulgar, lo que podr\u00eda ofrecer nuevas funcionalidades en el sistema <strong>Di2<\/strong>. Adem\u00e1s, el prototipo mantiene una arquitectura semi-wireless, con el cambio trasero conectado por cable a una bater\u00eda central.<\/p>\n<h3>Componentes y materiales<\/h3>\n<p>El prototipo conserva las bielas de aluminio, en contraste con la tendencia de otras marcas hacia el carbono. Las bicicletas fotografiadas muestran platos que no parecen ser los definitivos, lo que sugiere que este dise\u00f1o a\u00fan podr\u00eda evolucionar.<\/p>\n<blockquote><p>\u00abThanks to Quentin I could have the look before everyone else at new Shimano 13-speed Dura Ace\u2026 and now you can too.\u00bb<\/p><\/blockquote>\n<p>Este desarrollo promete seguir dando que hablar en los pr\u00f3ximos meses, ya que representa un avance importante en la tecnolog\u00eda de grupos de carretera de <strong>Shimano<\/strong>.<\/p>\n<hr>\n<p><em>Con informaci\u00f3n de <a href=\"https:\/\/www.brujulabike.com\/shimano-dura-ace-r9300-13-velocidades-vuelta\/\" target=\"_blank\" rel=\"nofollow noopener\">Br\u00fajula Bike<\/a>.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>El esperado prototipo de Shimano, con 13 velocidades, se estrena en competici\u00f3n durante La Vuelta a Espa\u00f1a 2026.<\/p>\n","protected":false},"author":1,"featured_media":2768,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[18],"tags":[],"class_list":["post-2772","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-bicis"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.4 -
