Aligera - Aerobarras

Lighten Up - Aerobars

Algo nos ha estado molestando en TriRig. Se podría decir que me pica un poco. ¿Cuál es nuestro problema? Creemos que las piezas aerodinámicas son demasiado pesadas. En la búsqueda interminable de una mejor aerodinámica, muchos fabricantes han perdido de vista otro aspecto importante de las piezas de bicicleta de alta gama: mantenerlas livianas. Claro, puedes vestir una parte con fibra de carbono, pero eso por sí solo no la hace liviana. Un ejemplo: el aerobarro Trek Speed Concept (barra base de carbono con extensiones de carbono) pesa alrededor de 750 gramos, ANTES de agregar las palancas de freno o de cambio. Dale una palmada a las palancas Bontrager originales y a las palancas de cambio R2C de SRAM (que son impresionante , por cierto), y pesas más de 1000 gramos. Por eso, en los próximos meses publicaremos una serie de artículos con la noción de que la búsqueda de la aerodinámica necesita "aligerarse", literalmente. Y vamos a empezar justo en la parte delantera de la bicicleta.

Abrazando a tu interior Weight Weenie

 

¿Por qué estamos en una loca búsqueda para aligerar nuestras bicicletas? El peso no lo es todo, por supuesto. Existen buenos recursos para determinar qué tipo de ventaja de tiempo obtendrás en qué tipo de terreno al tener una máquina más liviana. Pero no estamos realmente interesados en cuantificar esta loca búsqueda. Si pudieras tener una configuración frontal que pesara, digamos, la MITAD de lo que pesa la barra superior de Trek, todo lo demás igual, ¿por qué no lo harías? Además, las configuraciones mínimas tienen ventajas más allá de la mera ligereza. Analicémoslos. En primer lugar, una configuración mínima puede resultar bastante aerodinámica, como demostró Chris McCormack. a principios de este año . Menos material normalmente (si se hace correctamente) significa menos material expuesto al viento. Por supuesto, esto significa que la propia barra puede sacrificar algo de capacidad de ajuste, pero no olvide que la capacidad de ajuste se puede lograr en otros lugares además de la propia barra (es decir, elección del marco, elección de la potencia).

Además, una barra de carbono de una sola pieza probablemente será sólida como una roca. Una barra con una docena de pernos y varias piezas de hardware puede resultar torpe y engorrosa de ajustar. Preferimos obtener una relación adecuada entre almohadilla y extensión en la propia barra y luego lograr una pila general mediante el ajuste del marco y la potencia. Con eso en mente, nos propusimos crear el sistema frontal más liviano posible.
