I've just bought a bike fitted with a pair. I'm told they all do they all do that ? Something to do with this shpiel...
Enhanced comfort and shock-absorbency levels are provided by tuning the carbon-fibre lay-up so that the fibre orientation provides just the right amount of axial resilience and bonding these to high specification tubular steel spigots, permanently fixed into the new oval arm Monobox crown. The elastomer rings visible between the underside of the crown and the carbon lowers can then deform as the forks steel spigots flex under axial load.
is that the noise it makes when what they've said up there ^^^ happens ?
