The Wolf Tooth "Performance" MTB Headset Top Cup - EC34/28.6 - 16mm Stack is the top half of the Wolf Tooth Performance headset for frames with external cups (EC34: 34 mm head tube inner diameter on top) and a fork with a 1 1/8 inch steerer, machined from 6061 aluminium in Minnesota. Wolf Tooth sells top and lower cups separately so any combination of head tube and steerer can be put together. The short 5 mm top cover gives a 16 mm stack including the 10 mm cup. Inside runs an Enduro black oxide steel bearing with a one year warranty, with a lip seal above it and an O-ring on the steerer; a stem cap with integrated 5 mm spacer, an aluminium bolt and a star nut are included, a carbon steerer needs a compression plug instead of the star nut.
