A bicycle fork and frame assembly comprising a frame having a head tube including an outer dimension, a fork including a fork crown and a steerer tube positioned in the head tube, an upper bearing, and a lower bearing having a diameter. The upper and lower bearings are configured to rotatably support the fork within the head tube. The head tube includes a first end proximal to the fork crown and a second end distal to the fork crown. A ratio is defined by a distance from the first end of the head tube to the lower bearing divided by the diameter of the lower bearing, and the ratio is at least about 0.20, preferably at least about 0.25 and more preferably at least about 0.30. The assembly can further include a transition coupling the fork crown to the steerer tube and defining a transition point between the transition and the steerer tube. The transition has an outer dimension that increases from the steerer tube toward the fork crown, and the lower bearing is located adjacent to the transition point. The steerer tube can include a lower section coupled to an upper part of the transition at the transition point and an upper section coupled to the lower section. Preferably, the lower section has an outer dimension that tapers smaller moving away from the transition (e.g., frustoconical), and the upper section has a substantially constant cross section (e.g., cylindrical). The fork crown defines an arch way that is a distance from the lower bearing. In this aspect, a ratio is defined as the distance divided by the diameter of the lower bearing, and the ratio is at least about 0.7, preferably at least about 0.77, and more preferably at least about 0.83.
