- Easy to Replace: You just need to use a hex wrench and it will be installed in a few minutes. The bar headset replaces the traditional star nut and top cap, a necessary part of a bicycle steerer.
- Good Performance: The bar headset eliminates the risk of damage and provides additional support for the fragile top edge of the steerer. It can be used repeatedly, bites tightly, and is a must-have for high-end bikes.
- Installation Instructions: First, you make the headset top cover key expand slightly into the inside diameter of the fork to prevent slippage. Then put in the fork and lock it tight with a #6 allen wrench, making sure the handlebar edge is about 3 cm higher than the spreader.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
