Headsets are really simple to get the right model if you measure accurately and follow the plan. Please dont guess and googling is often inaccurate. Unfortunately we dont have every bike ever built so its hard to offer better advice than just measuring your actual bike sat infront of you.

First step, Measure the INTERNAL diameter of your headtube in mm.

Second step, measure your crown race fitting diameter. old straight steerer is 30mm, taper is 40mm and supertaper 1.8" is 46mm

Third step, choose the colour you need.

For special tuning of your geometry we offer angle headset, reach headsets, extended stack cups and even extended crown races.

Note we dont support IS type headsets without cups and there are loads of random defunct sizes out there, but we do cover 99.9% of bikes so we should be able to help with your upgrade.

All our aluminium headsets are manufactured in the UK from high quality 6082 aerospace grade aluminium. We use Custom high waterproof grease fill sealed angular contact bearings with tight tolerances for long life and precision. Under load our headsets have minimal friction and are designed to last. With over 15 years of headset sales you can trust in our quality and long term support for fairly priced spare parts.
