Headsets

They’re hardly the most glamorous part of your bike, but headsets perform the important job of keeping your front end – and your steering – turning smoothly. Threadless headsets, where the stem bolts directly on to the steerer tube of the forks, are increasingly the norm, though traditional versions – with a ‘quill’ stem – are still in use. We have models for all types of bikes and riding, from Chris King, Hope, Cane Creek and other top brands, along with spares including headset caps and star nuts.
