In bicycles that have the front fork and handle bars attached to a steering tube that rotates within a frame mounted head tube, a bearing system wherein a compression ring slides over and about the steering tube to trap the bearing against the head tube. Lock nuts surround the tapered compression ring so that when they are threaded together they squeeze the ring against the steering tube. Threads or barbs on the inside of the ring dig into the steering tube to resist movement away from the bearing and allow the ring to be moved against the bearing and establish a proper bearing end load. Further tightening of the lock nuts holds the ring permanently in place.
