Extralite UltraTop Headset


Well known for their intricate designs and unique aesthetic, Extralite has been creating featherweight bike components for the last two decades. Focused on crafting parts for riders who demand the pinnacle of lightweight performance, Extralite shows that they can create one of the lightest headsets on the market.

The Extralite UltraTop offers a new take on reducing weight from your bicycle. Featuring a two piece design that allows use of a smaller lighter radial contact bearing, the UltraTop headset is one of the lightest headsets on the market utilizing a cartridge bearing. Available in every major headset standard, no matter your frame extralite makes a headset to fit. Also available in a heavy duty design featuring a full size cartridge bearing, the UltraTop headset offers an featherweight and an ultralight option that can be depended on with heavy usage.


To select the headset that properly fits your frame simply measure the Inner Diameter of the headtube on your frame and pick the corresponding headset. Check out Extralite’s page that has a handy table to view every option and special information about each headset.
