ROLLCii EC34/EC44 Threadless Sealed Bearing Headset

ROLLCii EC34/EC44 Threadless Sealed Bearing Headset

A good headset should disappear beneath the ride — smooth, dependable, and built to last. The ROLLCii headset is designed with that philosophy in mind.

Built using high-quality sealed cartridge bearings and precision-machined aluminum alloy cups, it delivers reliable performance for everyday riding, long-distance touring, and custom bike builds alike. The lightweight construction keeps things simple without sacrificing durability.

Available in a range of anodized finishes, the ROLLCii headset also adds a subtle visual detail to your build. Whether matched perfectly or mixed intentionally, the color options allow a little more personality without overwhelming the bike itself.

Clean design, practical function, and easy long-term serviceability — exactly how a headset should be.
