Abstract:
A fork assembly for a bicycle includes a pair of forks and a steerer tube that extend in generally opposite directions from a fork crown. The assembly includes first and second means for securing the steerer tube to the fork crown. Preferably, the steerer tube is threaded and bonded to the fork crown. The fork crown includes a pair of cavities that each slidably receives a respective fork. Preferably, each fork is formed of a carbon fiber material and has an end whose shape substantially matches a shape of a respective cavity formed in the crown. The forks and crown cavities cooperate to efficiently communicate loads between the forks and the fork crown while maintaining a lightweight and robust fork, fork crown, and steerer tube assembly.
