If it's like my Ritchey, you will need to take it off the bicycle - leaving the handlebars on. Start by removing the top-cap on your headset. Loosen the bolts on the stem and slide it up & off. Then loosen the silver bolt on the adj. stem. From there it should be able to be adjusted to the height/angle you wish. Re-tighten the silver bolt and slide it back on the steering-tube. Tighten the bolts TIGHT and replace the top-cap. Adjust that until the handlebars turn freely when you tilt the bike towards the ground - but not so that it's loose. Make sure by applying the front brake and, holding by the middle of the handlebars, push the bike (on the floor) back and forth. Make sure there is no play.
