The invention relates to a bike stem and more generally to a stem for connecting a steering bar to a steering tube. The stem body is substantially hollow allowing the use of a locking member to engages the handlebar on one end and the steerer tube on the other end and can be secured by tightening bolts on only one end of the bike stem, thereby exerting pressure on the handlebars and to the locking member, which thereby applies a force to the steerer tube, securing the steerer tube to the bike stem without the need for bolts on the steerer tube side of the bike stem.
