New range of high quality headsets in totally weird sizes!

ZS cups for standard tapered forks in 55, 62 and 66mm

ZS59 cup for standard tapered forks in 59mm for getting rid of the weird ball gimbals which break on some Marin Alpine trail XR and Whyte bikes

EC56/46 to turn your older frame into Supertaper 1.8" fork compatible by having an external bearing (reduce race to 40mm available)

EC56/40 to rake out your headangle by lifting the front of your bike 15mm. A nice alternative to angle or reach headsets. Make sure you have enough steerer length!

Manufactured to the highest tolerances these headsets are a perfect fit and forget multi-sealed replacement for the cheap and nasty product normally fitted to complete bikes to keep manufacturing costs down.

Fully sealed cartridge bearings and custom made NBR wiper seals keep out the dirt and water, giving you a long lifespan in the worst conditions. An innovative retained compression ring and aluminium split crown race makes assembly easy.

Precision CNC machined from 6082 T6 heat treated aluminium. Pick and mix to suit your frame.
