• Ok, it's carbon, because I can see some black fibres. Not glass in black resin, at least round the rim anyway. 3k weave on the bits round the rim that I can see. Wet layup because there are some dry looking fibres. Nice hub, but... it's bonded in the wrong way round! So it's got backwards aero, lol. I'm sort of tempted to skin it with 0.3mm cf and run it as a disc.
