mi burra pesa eso el cuadro... 1.9kg por ahi por ahi... Yo me acuerdo que a los Kona Explosif les tocabas al pedalier y parecía que salía corriendo de lo que flexaba.
puff q tema. yo creo q me quedo con el ti,pesa mas pero aguanta mucho mas. mirar el cuadro de carbono de las merida,q pasa muy sobrado los 1600 o el trek,pues apra eso ti,q ademas aguanta mucho mas. aunq es cierto q depende dle material,pq las tias ams ligeras son de alu y no de carbono, y los amnillares son de carbono,y lso tornillos de ti. :loco
Dr.power, y cuanto resisten??dnd lso venden??por cuanto?? :mrgreen: aunq is quereis ahorrar peso ,dejaros de tornillos de carbono o ti,q so mariconadas,nada como el superglue. :mrgreen:
Schmolke Carbon bolts 8.- up to 9.50 Our screws are manufactured in a highly specialised pressure extrusion procedure. The material used is our own high quality Intermediate module fibres with PEEK-matrix. This is the only means to make sure the fibres are arranged in a spiralling pattern following the thread and centred towards the inside of the screw. The actual thread can not be stripped. In terms of dynamic strength carbon fibre is much superior to all other materials used for screws. They are stronger and 40% lighter than aluminium bolts. Screws may be used anywhere where aluminium screws or bolts are sufficiently strong. They are particularly recommended for bottle cages, rear cantilever bosses, brake pads, front derailleur, rear derailleur pulley wheels, MTB brake levers, ahead cap, stem to fork clamping and similar. They are not to be used for stem/handlebar clamping and saddle or seat posts! Our screws do not need to be tightened up as much as metal screws, they expand more when tightened, and hence they are less likely to become loose. Since they also suffer less from friction in the threads they do not need to be tightened with as much torque as a metal screw to achieve the same internal tension. If you further want to increase internal tension without raising the torque add grease to the thread and the bottom of the screw's head. Tool to be used is Torcx 20 only, it offers best transmission of force. At this moment the following sizes of screws are available: M4x16 0.8 Nm 0.5 g 8.- M5x20 1.5 Nm 0.7 g 8.50 M5x20 countersunk 1.5 Nm 0.7 g 8.- M6x30 4.0 Nm 1.3 g 9.50 M6x16 countersunk 4.0 Nm 0.7 g 8.-
El carbono es menos denso -> a igual volumen pesa menos. Otra historia es q fabriquemos una pieza q aguente lo mismo en carbono y titanio, ahí ya no se q puede pesar menos.
Yo los cuadros de acero mas ligeros que he visto llevaban tubería Columbus Foco, y pesaban menos de 1.400 Gramos. En Lightbikes.com hay una de ellas y ademas en una talla bastante grande, la Marca es Ferrous. Un saludo.
entonces x lo k veo l carbono pesa bastante menos k el titanio,pero aun asi la gente prefiere titanio??? :roll:
