Product Description

Prdocut Description:

A bike headset is a component of a bicycle that connects the fork to the frame and allows for steering of the front wheel. It consists of several bearings and races that allow the fork to rotate smoothly in the frame's head tube. The headset also helps to absorb shocks and vibrations from the road, improving the bike's overall comfort and stability. The threadless headsets have a smooth steerer tube and clamp onto the fork using a system of spacers and a compression cap.

Our headset includes all the necessary parts including star nut, compression ring and bolt, cups, sealed bearings and crown race, top cap etc.

Measure the head tube and fork tube dimensions to ensure the compatibility

Got this today and it took about an hour to install, which went as smooth as the sealed bearings included in this headset. I'm stoked that it fit so well and the feel is like having a brand new bike again! The sealed bearings are smooth, silent and responsive while the rest of the hardware fits seamlessly and compliments the steering and fork components much better than what was on there before. I'm really happy with this product and would recommend it as an easy and affordable way to upgrade your bikes performance and look.

This is definitely a quality, machined, aluminum headset It comes with everything you need, including the star nut that sits inside the fork in case you don’t already have one. It comes with a cap and then it comes with the sealed bearings, nice machined quality aluminum. it’s very eye-catching, and a good way to make your bike appear more fancy, I recommend this product to anybody looking to customize their bike
