The GeoShift Performance Angle Headset allows you to adjust the geometry of your bike by changing the head tube angle, available in 1 or 2 degree options. This unique design lets the bearings sit at an angle to align with the steerer tube, preventing creaking noises commonly found with angle headsets that feature a spherical design. Reduce the head tube angle to make for slacker geometry and added stability on fast descents, or increase the angle using the opposite orientation of the headset, to make for steeper geometry and quicker steering with maximum front wheel traction. - Enduro black oxide coated chromium steel bearing included on both the upper and lower - Upper headsets ship with a star nut which can only be used on forks with steel or aluminum steerer tubes.

1-1/8 Black Oxide, Angular Contact, External Bearing Kit for 34mm (1 1/8) ID head tube framesets This unique bearing kit eliminates the external headset bearing cup and provides a simple low profile solution where the bearing itself presses directly into the head tube. The kit includes fork crown race and upper split-ring and cap. These bearings feature anti-corrosion Black Oxide/Magnetite alloy races paired with grade 10 Balls, dual-lip labyrinth (LLB) seals to withstand the outside elements, and to contain water proof synthetic grease. Black Oxide coating provides an extra level of corrosion resistance and extended worry free performance. Color: Black SHIS: EC34/28.6 | EC34/30 Vendor Part # HDK-0007

1-1/8 Stainless Steel, Angular Contact, External Bearing Kit for 34mm (1 1/8) ID head tube framesets This unique bearing kit eliminates the external headset bearing cup and provides a simple low profile solution where the bearing itself presses directly into the head tube. The kit includes fork crown race and upper split-ring and cap. Enduro only uses 440C stainless steel balls and races to provide long life and superior corrosion resistance in applications and environments that may be less than ideal. Stainless steel is an excellent alternative for use in wet conditions, if you wash you bike often, or where sweat can be a problem. Enduro Bearings also uses LLB type seals and CRC Marine Grease in these bearings to additionally water proof against the elements.. Color: Silver SHIS: EC34/28.6 | EC34/30 Vendor Part # HDK-0008

These baseplates are the foundation that keeps Chris King headsets turning with legendary smoothness. Manufactured from high-quality stainless steel or titanium, Chris King makes replacement baseplates for all standard sizes and a number of ingenious solutions for those that need something a little special to make their headset work. - Engineered and manufactured in Portland, Oregon USA - Devolution baseplates are a stainless steel solution that allow Chris King headsets to adapt to a wide variety of steerer tube sizes - 30.0mm for 1.5 lower bearing and 1 1/8" steerer

Why We Make This: The simple answer is that many contemporary bicycle frame designs call for the headset bearings to ride inside the frame’s headtube. After decades of making press-in bearing headsets, we needed to make headsets that worked in these newer frames. From the beginning we understood that integrated headsets posed a unique challenge in that the bearings are not pressed into a cup and sit loosely in the frame. When bearings are not pressed securely into a cup they shift and move, rapidly losing preload. As preload drops, the bearings are more susceptible to creaking, damage, and failure. That’s a problem we know how to solve. Why You Want It: Enter, our patented GripLock™ bearing cap. The GripLock™ preloads the headset independently of clamping onto the steerer, so it retains preload far better than the competition and is impervious to the ill effects of load spikes from large hits and heavy braking. This means smoother steering, no more creaking, and a longer lasting headset. Our GripLock™ design also takes the guesswork out of preloading a headset, because the bearing preload force is independent of the clamping force. Our headsets can be preloaded to a torque spec. Compatible with Open, 3T, All City, Low, Cinelli, Lynskey, and more. - Engineered, manufactured and assembled in Portland, Oregon USA - King Lifetime Warranty - Legendary made-in-house bearings - Patented GripLock® retention design for dependable headset adjustment (US Patent 8662517) - 42mm 45x45 upper bearing for 2.8-3.0mm bearing ream depth. - 52mm 45x45 lower bearing - Compatible with our included baseplate and 45 degree integrated crown races

The Inset headset offers Chris King's trademark quality and durability in a low-stack configuration sized for contemporary headtube dimensions. King's legendary made-in-house bearings still form the centerpiece of the Inset headsets, with precisely machined aluminum cups and headset caps available in all ten classic Chris King colors. The Inset 2 is compatible with tapered 1-1/8 - 1-1/2-inch forks and frames using a 44/56mm headtube.

Why We Make This Contemporary bicycle frame designs are incorporating larger diameter headtubes and forks with tapered-steerers to improve the bike’s front end stiffness, and as a result handling accuracy. This move has made particular sense for off-road bikes. We evolved the form and function of our legendary NoThreadset to address the variety of tapered steerers and headtubes on the market today. Why You Want It Every Chris King headset is built with our heat-treated bearings, and surgical-grade steel races machined simultaneously to ensure they are perfectly matched. As Chris King bearing tracks age and burnish, they actually get smoother, and all headsets are fully serviceable for years upon years of demanding riding. Built for the next generation of tapered road forks the Chris King InSet™ 8 is built to fit contemporary road and cross bikes that utilize 1-1/8” to 1-1/4”tapered steerer tubes and a 44mm headtube. Our InSet™ 8 combines our exclusive Chris King built bearings and our GripLock® retention system for unequalled riding quality. - Engineered, manufactured and assembled in Portland, Oregon USA - King Lifetime Warranty - Legendary made-in-house bearings - Patented GripLock® retention design for dependable headset adjustment (US Patent 8662517) - Responsibly lightweight - Designed specifically for a 44mm straight headtube and a 1-1/8” to 1-1/4” tapered steerer tube
