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

This was a perfect fit for my Ghost mountain bike, and better than the original open bearing retainer cages that it replaced. This appears to be a well-made product with closed bearing rings. I will update this review if I encounter any issues over the next several months.

I used this set on my Motobecane Fantom mtn bike. This set is better than the original open cage bearings. This has sealed bearings and all other parts for an internal setup. Well made; fits correctly. Works great so far!
