FSA Standard Headset Bearings

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 Santa Cruz, Yeti, Alchemy, Santa Cruz Stigmata (without baseplate), Ibis Hakka MX, 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) - 41mm 45x45 upper bearing - 52mm 36x45 lower bearing - Compatible with the included baseplate and 36 degree integrated crown races

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.

Our headsets have three levels of industry-leading custom sealing to protect bearings from the elements and prolong the life of the headset. This has a stack height of 3mm and is available in a variety of colors to match other Wolf Tooth anodized color options. These IS headsets are made exclusively for Specialized frames with molded-in internal bearing cups. Like all Wolf Tooth Premium Headsets with Enduro stainless steel bearings, the Premium IS Headset for Specialized has a lifetime warranty. Compatibility - Any Specialized bike that uses an IS (Integrated Standard) headset with 42mm upper bearing diameter. - Uppers and lowers sold separately. - Enduro stainless steel sealed bearings 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. For forks with carbon steerer tubes you will need a compression plug (sold separately). (Never use a star nut on a carbon steerer tube). - Some bikes, like the Stumpjumper EVO, have an adjustable headset that resembles a ZS headset where an upper cup is pressed into the frame. Our bearing will fit into that cup and our top cap will fit neatly on top. Measuring to determine compatibility with your Specialized frame 1. Disassemble the headset, remove upper bearing from the frame 2. Use the depth blade on a caliper to measure from the top of the headtube to the corner where the 45 degree taper starts.
