V12man Posted February 18, 2015 Posted February 18, 2015 he down side is the cost and there are but a handful of us skilled artisans left who will work with mag.How is your mag welding? feel up to repairing some 914 rims for a friend?
Wil6 Posted February 19, 2015 Posted February 19, 2015 Bloody hell what happened to that crank! As for carbon vs Alloy, go and ride the two and you will immediately feel the difference in stiffness and the response you get out of the bike. Then there is the weight you save. And it looks nice like mentioned above
rouxtjie Posted February 19, 2015 Posted February 19, 2015 Better is relative to each application https://community.bikehub.co.za/topic/147878-titanium-bikes-salook at post 9. For racing, carbon would be first choice...remember carbon's weight isn't what make it the best, its the material's stiffness where watts are not lost in flex.
Robrider Posted February 19, 2015 Posted February 19, 2015 Carbon can be repaired. Part of what I do is make products from carbon fibre. The trick is to have an autoclave. I fully agree with the weight issue though, the difference is very slight. If you want the same weight in ally then look for a frame made from the 7000 series alloy. Better still magnesium. Magnesium properties are 2/3 the weight of ally size for size but more than double the strength and rigidity. The down side is the cost and there are but a handful of us skilled artisans left who will work with mag. Scandium frames are probably the lightest aluminium frames on the market. Kona has a few and they are lighter than many carbon frames. Carbon can be repaired, but I don't see the point (besides restoring your expensive bike).The benefits of carbon are the lightness and the way the layering can be done to improve the ride dynamics of the frame. A repair will make it both heavier and will change the ride dynamics due to the layering not being in the same direction as the original. Don't get me wrong, I'm not saying it will be weak or comprised. But people often claim that the bump absorption qualities of carbon make the ride better. Surely a repair will change that. Moral of the story... Scandium.
floatfox Posted February 19, 2015 Posted February 19, 2015 A lot of guys make the mistake, thinking carbon is purely for weight saving. It also gives you a much softer ride. So its not only about weight.
