How would i go about doing this. Do i need to know each individual spoke size. The spokes on the wheels are double butted straight pull fulcrum racing 3 wheels. Anyone give me some insight if i decide to do this. Is it worth doing to save the weight, How much lighter is titainium straight gauge vs steel double butted? The wheels have steel double butted. Im thinking about puting titainium straight gauge to replace them. Worth doing or not worth doing?
