Cane Creek AngleSet ZeroStack/External Cup Headset Kit

Adjusting your head-tube angle changes the bike's geometry, which directly impacts how it handles. Slackening the angle (negative degrees) increases stability at high speeds and on steep descents, while steepening it (positive degrees) makes the steering feel quicker and more responsive for tight, technical trails.

This kit is designed for frames using a tapered 1-1/8 to 1.5-inch steerer tube with an external cup standard. Because head tube standards vary significantly, you should confirm your frame's specific headset cup requirements before purchasing to ensure compatibility.

The installation is slightly more involved than a traditional headset because the AngleSet uses a gimbal system to accommodate the angle change. You will need a standard headset press, but you must be precise with the alignment of the cups to ensure the bearings seat correctly and the adjustment functions as intended.

Yes, the headset uses black-oxide sealed cartridge bearings paired with high-quality seals. This combination is specifically engineered to resist corrosion and prevent dirt and grit from contaminating the grease, making it a reliable choice for aggressive mountain biking.

No, the AngleSet is designed to be set during the initial installation. Once the cups are pressed into the frame, the angle is fixed; you cannot adjust the angle on the trail without removing and re-orienting the headset cups.
