Replacing the stock ball bearings in the steering head with tapered roller bearings is, in our opinion, a must. They allow better adjustment, last longer and handle steering loads much better. BikeBandit.com sells excellent kits from All Balls, which include spacing washers. Follow the directions that come with the kit to determine which spacing washer to use on your bike. In our case, we had to use the thicker of two washers. Pack the bearings by putting a glob of grease in the palm of your hand. Drag each bearing down through the grease and toward your wrist, spinning the bearing and filling the crevices with grease until they look like the bearings shown here.
