I think you're the one not getting the main point, you're bashing carbon fiber however the material used in the product has nothing to do with this, you can have a 1.5 or a 1 1/8 headtube on a carbon frame. The problem is like Joe Graney from SantaCruz says, when a brand has nothing new to offer, they "attach" a new technology to their product so it looks like a new product. This has nothing to do with lowering weight or increasing strenght or stifness but a form of marketing. Carbon is to aluminium what aluminium was to steel. Your comment doens't make any sense, first you bash new products and spending $ for products the buyer doens't need and then you say you support this new technology? This tecnhology is useless and only creates incompatibilities which make prices higher because the less 1.5 or 1 1/8 headbutes are being used the higher the price of their headsets because something that isn't standard is always more expesive. Carbon fiber is 3 to 4 times more expensive than aluminium however you're not paying 5000 USD nor 7500 USD or 10000 USD for a carbon frame, its just a little more than an aluminium one. You can bet that a brand has a higher profit margin on aluminium frames than on the carbon ones. So you bash carbon fiber that creates no incompatibilities and you support this and other types of headtubes that creates incompabilities. This is plain stupidity, no offence.
