Con lo trasto que son la Mondraker y lo dura que es tu cabeza, no me extraña que lo arrugaras....... :lol: :lol: :lol: :lol:
great discussion, I didn't expect to have uncle Roger writing here! that's cool! Welcome to one of the "badassest" places in foromtb... Coming back to the issue of ceramic coating rims. That looks as an interesting option... guys here are worried about getting warped or distorted rims due to the temperature. Have you get any experience on that? By the way, is the coating that you'd apply the same type that the one used on ceramic rims? (hoping the same type of braking pads are suitable). What a plessure having you here... that's very good for nerds like us... I am coming with a new weird option. What about ceramic coat an aluminium disc rotor that I might order with my own design to a laser cutting workshop?
Again thank you for welcoming me to join in your discussions. The ceramic I use is more suited to aesthetics, protection from the elements, and to inhibit mechanical surface wear, such as rings and cassette. The ceramic used for rim brakes has been formulated to not have self lubricating properties as my ceramic does.
Ok, I got you... then it is a "nonsense" for breaking parts, but very suitable for transmission bits and "pimping" the bike with luxury color coatings :aplauso4 But then, :melopien:, suspension fork stanchions should be like a perfect application as well??!! Even more in the vintage forks, where you normally can disassemble the stanchions from the fork crown and then coat them in a very "clean" way...
Exactly, the ceramic is the best protective coating you can apply. It resist corrosion, wear and abrasion, heat, chemicals, uv. It can be used for internal and external engine treatments too, ie, pistons, crankshaft, valve train. Anywhere there is surface to surface friction. I have coated several forks stanctions and tubes it does work great for this application. Have also coated a few frames. The ceramic is very light weight too. Check out the modified XTR 960 arms made for Mattias. His rings look fantastic in the 2X set up. 672grams not bad.
Yeah! I am a customer of Mattias myself. I have two sets of "transparent" Ti chainrings coming from Dalarna (Sweden)... But then, coming back to the ceramic coatings... I do know many of the applications are connected to trybologic improvements, so reducing friction and improving wear properties are normally the intention when such coatings are applied. On the other hand a brake system is more connected whith creating even more friction so the breaking performance is improved, apparentely opposite ideas... So, the only explanation to me for ceramic coatings in breaking surfaces, like rims and rotors, is to protect the substrat (we talk about soft aluminium in most of the cases) from severe wear. And because the special low friction properties, I guess it makes necessary the use of special braking pads to recover some lost friction...
Esas Bielas eran en mi opinión las mas feas de toda la historia del XTR, peeeeeero una vez tuneadas se convierten en una de las mas guapas de la historia. Un saludo.
Donde se puede conseguir informacion de Mattias,llevo un rato navegando y he visto cosas chulisimas pero no doy con la web.
Mirando mirando, puedo hacerme con unos brazos de unas bielas XTR (solo brazos) modelo nuevo, pero bastante perjudicados por el roze de las zapatillas y algun golpecito. Viendo la posibilidad de como aprovechar este material, habia pensado en pulirlos, pero luego me acorde del proceso "ceramizador" este, lo que no se si merecera la pena, y si teneis alguna idea de que poder hacer.
Estas bielas, como sabeis tienen una zona en color alu y otra en negro, mi idea era dejarlo todo en algun color, supongo que se podra, no ??
The XTR 970 arms are two tone, a dark blue/black with a brushed face with a clear coat over. It's possible to coat them one color or again two tones of ceramic. I have a set that has been coated one color, ti blue metallic.
Thanks for your reply. The possibility of two tones of ceramic coated is isteresting, too. Could you show us this picture ??? And just another question, how much weight is added, aprox. in a set of arms, after a ceramic coating ?? Thanks in advance.
