Las fotos en donde se aprecian los grosores de los tubos seccionados me parecen increibles y muy muy didácticas, ¿alguién sabe dónde puedo ver más fotos de este tipo de la marca que sea?
Hola. No había visto las fotos y fíjate que ya llevo tiempo buscando. A ver si este año, al igual que el pasado, también damos pronto con el catálogo completo. De momento no tiene mala pinta lo que nos enseñas, estéticamente me esperaba algo más aunque seguramente que en el tema de funcionamiento sea donde está la mejora. Gracias por las fotos. Un saludo
Bueno señores, acabo de encontrar una cosa.... http://www.sicklines.com/2007/06/08/dave-weagle-launches-new-suspension-system-split-pivot/ Parece ser que trek no ha inventado este sistema sino que es un diseño de Dave Weagle, el del DW-Link... Este tio por lo que se ve es un genio. Ahora si os fijais en el anclaje del amortiguador todo tiene sentido: No es que se hayan copiado de KTM, es que a DW le gustan mucho este tipo de soluciones: La IF Doble iba exactamente igual y las IronHorse a veces comparten pivotes con anclajes del amortiguador. Un saludo.
No, pero coincido en que el tio Dave es una máquina, ese tipo de soluciones aparentemente sencillas son las que vuelven locos a los otros ingenieros que piensan ¿por qué no se me habrá ocurrido a mi?
En mtbr hay un link a ridemonkey.com donde discuten el nuevo sistema y parece que el propio Dave W les responde ¿? http://www.ridemonkey.com/forums/showpost.php?p=2567709&postcount=70 "Wow, damn, let the speculation begin! Those of you with kind words, thanks for the support, I truly appreciate it. Haters, well, its a tough life I guess. So bottom line with this system, it is a single pivot for acceleration purposes, a multi pivot for braking purposes. In reallity, performance wise it can exactly duplicate what most FSR bikes have done. With a little knowledge (i.e. pivot placement) I think that it can outshine many of the FSR bikes that have been built. The raw idea is that I use a single pivot location that offers some real benefits for acceleration purposes, but without a floating brake this pivot location that works so well for acceleration would have some real drawbacks under braking. This is where the Split Pivot (the concentric dropout pivot) comes in. The seatstay link and assembly acts as a floating brake arm, exactly like FSR does. Nothing new there at all. The pivot location around the axle is the novelty and why I had to apply for patents etc... Is this bike going to be better than a dw-link bike? Sadly, no. Is it going to ride better than a single pivot or other linkage bikes? I believe completely that it has the ability to. No matter what, Split Pivot can be used to build a pretty light bike with good performace characteristics. There is nothing wrong with that in my book. Dave" This was a very important factor in developing this design. Split Pivot is not intended to replace or compete with dw-link, just complement it. how can a "linkage actuated split pivot" design, as shown, be lighter and less expensive than a comparable dw*link design? Manufacturing tolerances. A dw-link needs to be held to tight tolerances to perform as designed. This usually menas CNC machining the entire weldment after heat treat, or pretty careful fixturing and alignment. 1mm is a huge number in dw-link world. A Split Pivot could be welded by a monkey and still probably work out allright. 1mm is practically inconsequential with Split-Pivot. I don't think that Split Pivot could be lighter than dw-link in an ideal world. dw-link is structurally pretty hard to beat."
