<p>There is described a bicycle having a steerer tube (3) mounted to the bicycle frame in upper and lower annular bearings (5, 4). Fork blades are mounted to the lower end of the steerer rube. The steerer tube has a non-circular cross-section at the location of the upper bearing (5). A headset (2) is clamped to the steerer tube and is supported in the upper bearing (5). The headset may be clamped to the steerer tube by means of clamp screws (9) engaging with a guide wedge (10). A passage passing through the upper bearing (5) is defined between guide wedge (10) and the steerer tube (3). Control cables from controls on the handlebar may pass through the passage and into the interior of the bicycle frame (7). Control cables may also pass through the lumen of the steerer tube (3) and into the interior of hollow fork blades.</p> |
