A bike headset is an essential cycling component that enables the handlebars to steer precisely and smoothly. A bike spacer allows you to adjust the handlebar height and find the perfect fit for you. You can DIY replace and install both, but it’s important to have quality parts (that suit your bike) to begin with. We stock a huge range of bike spacers and headsets from world-class brands, including BBB Cycling, Campagnolo, and Hope. Browse and buy below.
