FatCones have the same initial stability as a Barrel but as you lean, they offer progressively higher resistance the further you go.
WFB™ Formula: World’s Fastest Bushings
This compound has a unique lubrication added that does not bond with the urethane which is why you will often see a white residue on the surface. This compound offers reduced bushing friction for fast transitions and a deeper lean than the APS. WFB will turn 15% to 20% more than the same durometer of other brands. WFB also offers lower rebound than APS and is designed for the rider that wants a very fluid response. Truly the bushing of choice for the more experienced rider that wants to control his bushings instead of the bushings controlling him or her. Like APS, the WFB compound does not change much when you tighten the kingpin nut past snug. We recommend tightening to the point where it is difficult to turn the bushing in the bushing seat by hand. Use a flat washer for lower resistance and a cupped washer for higher resistance.
