CeramicSpeed OHD Kit for Giant Overdrive 2

SLT stands for Solid Lubrication Technology. Instead of traditional grease that can wash out or degrade, these bearings use an oil-encapsulated plastic polymer that stays inside the bearing, ensuring consistent lubrication without the need for maintenance.

No, you do not need to add grease to the bearings themselves. Because they are self-lubricating, they are ready to install right out of the box. You may apply a light layer of grease to the bearing seats in your frame to prevent creaking, but the bearings themselves are maintenance-free.

These are specifically engineered for the Giant Overdrive 2 standard, which uses a 1-3/8 inch upper bearing. They will not fit standard 1-1/8 inch or tapered 1-1/2 inch headtubes, so please verify your specific bike's headset specifications before purchasing.

These bearings are significantly more resilient in wet or harsh conditions. The combination of stainless steel materials and the solid polymer structure prevents the internal corrosion and lubrication washout that typically causes standard bearings to seize or feel gritty.

While the primary benefit is longevity and reliability, you may notice a smoother, more consistent steering feel. Because the lubrication is constant and doesn't degrade over time, the bearings maintain a consistent resistance level throughout their lifespan.
