Hace unos dias atrás la gente de Shimano dió a conocer su nueva linea XTR 2011.
Acá está toda la info (en Inglés) y fotos de los nuevos componentes:
As suspected, the 2011 Shimano XTR group has gone 2×10…but that isn’t all that’s changed!
Shimano recognized the changing mountain bike landscape, and the new XTR has a host of fresh technologies that let you tune the mix of components to suit your riding style, whether you’re riding trail and all mountain or racing your legs off on the XC circuit. Called “Rider Tuned”, the new parts mix offers different gearing ranges, types of brakes and pedals and settings on the components to tune their performance for the trail in front of you.
The most obvious change is the switch to Dyna-Sys 10 speed in both double and triple crankset options and the sharp edged new look, but there’s so much more to it than meets the eye. From all-new Ice Tech pads and rotors to a completely redesigned shifting mech called VIVID Index, XTR has broadened its reach.
Oh, and it also dropped weight. In its lightest configuration, it drops 200g (!) from the previous generation. In its heaviest, its still 60g lighter. The icing on the cake? All this new technology and lightweight goodness comes at you with no price increase over the previous group.
Check out all the goods after the break…
NOTE: Scroll all the way down to see some of these components on the bike with close-up, detail shots.
Starting with the most visible component, the crankset shown at the top of the post is the FC-M980 double. The M980 cranksets are available in both double and triple (full specs directly below) and are geared with trail riding (formerly known simply as “mountain biking”) in mind, but they all get the Chinese throwing star look of their current brake rotors. Here’s the triple:
The all-new AngleSet threadless headset from Cane Creek makes it possible to change your game. You can now transform the head angle of your mountain bike with ease, as the low-stack-height AngleSet offers up to six offset angle adjustments. With steeper or slacker adjustments from 0.5 to 1.5 degrees, dialing in the perfect geometry to attack the trail is a breeze.
The patent-pending design of AngleSet is head-tube length independent and fits most popular head tube standards. A self-aligning feature between the bearings and the steerer tube ensures a perfect fit and makes fork installation a snap.
This innovative technology is another way Cane Creek is helping you change your game.
La talla se expresa en pulgadas o en centímetros y corresponde, dependiendo de cómo mida el fabricante, a la distancia entre el centro del eje de pedalier a la intersección del tubo del sillín con el horizontal, o hasta el tope del tubo del sillín, o hasta el centro virtual donde cortaría un tubo horizontal.
Por todo ello, decir que tu talla es una 17″ puede que te sirva como referencia, pero es probable que en ciertas marcas Read the rest of this entry »
Para los que aún dudan de la efectividad de una horquilla Lefty, aquí les presentamos este video que ha preparado el maestro “Larry” sobre el funcionamiento de una horquilla estandar con casquillos de fricción, y una horquilla Lefty con rodamientos de agujas. Como verán en el video, la presión que se ejerce entre barras y casquillos, impide el normal funcionamiento de la horquilla. Esta presión no afecta a las lefty, de ahí su precisión de dirección y rigidez extrema.
