Box Two 45x45 Threadless Headset
Box Two™ 45×45 Threadless Headsets have an aluminum top cap, upper bearing cover, lower race and upper and lower cups. All-aluminum construction results in a lightweight yet durable headset. Each headset is fitted with super-smooth rolling, precision, 45×45 angular-contact sealed bearings. Because this versatile headset has 45×45 angular-contact bearings, you can use the included cups and install it in frames with standard head tubes. Or, leave the cup in the box, and use it as an integrated headset.
