There is no simpler way to lose some weight and add some bling to your bike than swapping out an alloy headset spacer for an M-Part Carbon Fibre Headset Spacer in 1 & 1/8 inch flavour. It really is that simple. Take out some heavy metal spacers, put in some M-Part Carbon Fibre Headset Spacer and your 1 & 1/8 inch steerer tube will be carrying a bit less weight, while your bike will look a teeny bit classier.
