About this item
- 1.【Quality material】: The handlebar disc adapter is made of an aluminium alloy. This material is strong, lightweight and durable. It has a higher resistance to oxidation and does not lose its colour easily. It is rust and corrosion resistant and suitable for long-term use.
- 2.【Wide Application】: Bike stem shims are suitable for bicycles and mountain bikes, handlebar brackets, car lights, rear view mirrors. You can mount 25.4 mm handlebars on 31.8 mm stems and easily adjust the handlebar diameter.
- 3.【Package Included】: The delivery includes four red handlebar adapter washers with a diameter of 25.4 mm, a height of 14 mm and a thickness of 5 mm.
- 4.【Easy to use】: When mounting your bike, if the stem diameter is larger than the handlebars, simply place the aluminium alloy shim spacers between the handlebars and stem. Then tighten the screws.
- 5.【CNC cutting technology】: The bicycle handlebar washers are manufactured using the CNC production process. The surface is flat and the edges are rounded and smooth. By placing two washers on the handlebars, a firm and tight connection to the bike can be created. This increases safety and stability when riding.

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.
