About this item
- UNIVERSAL SIZE: Aluminum alloy headset top cap bike fork expander bung for 28.6mm / 1.1in. Core Expansion Range: Approx. 22.2-25.4mm / 0.87-1.00in. Basically compatible with most of the bike front forks on the market.
- EASY TO REPLACE: Just use the hex wrench and then you'll get it installed in minutes. Replaces conventional star nut and top cap, a must for bike steerers.
- GOOD PERFORMANCE: Eliminating the risk of damage and providing added support to the fragile top edge of the steerer. Can be used repeatedly, bite tight, does not hurt the fork, a must-have for top-grade bicycles.
- INSTALLATION INSTRUCTIONS:Make the headset top cap key expand slightly to the inside diameter of the front fork to prevent slipping. Then put it into the front fork and lock it with the No. 6 inner hexagonal wrench to ensure that the handlebar edge is about 3 cm higher than the expander.
- GUARANTEE: If you are not satisfied with our product you received, you can send emails to us at any time. We will reply you instantly and help you solve your problem.

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.
