1-1/8" Headset Spacer Set. Inside diameter:28.6mm

The Bike Headset Spacer is made of high-quality aluminum alloy material, eco-friendly, sturdy and durable to use.

Lightweight and easy to install, having advantages of smooth surface and exquisite workmanship.

Why aluminum? Firstly, the difference in weight between 20mm of carbon spacers vs alloy spacer is far, far less than 1/2 ounce. It may be a gram or two. Secondly, The only glossy woven carbon part on the bike are the spacers looked weird. Thirdly, cheap carbon fiber spacers cannot meet the strength requirements of the high stress parts for sports bikes, experts recommended Tensile modulus 200-280Gpa, Tensile Strength 2500Mpa at least. Cheap CF spacers is fragile and even not cut evenly.

Why u need bike headset spacers ? Put simply, headset spacers enable you to easily adjust the height of your handlebars, which is an essential element of bike fit for MTB, BMX and road riders. In the particular case of the latter (road cycling), the correct bar height is key for comfort and performance.

Why 6 piece? The 2 mm, 3 mm, 5 mm, 10 mm spacers make it easy to have a precise height adjustment, the six piece of spacer can add 40mm height totally, that enough for most situations. If you just need 20mm or 25mm, you can still have some backup for more inflexible.
