February 15, 200719 yr Author Question: raising handlebar height A quick question, how do you raise the handlebar height? I have increased (or decreased depending on your point of view) the angle of the handlebar holder (the diagonal piece that links the handlebar post and the handlebars themselves) so it is pointing upwards but would like to know if it is possible to raise the post height. I only need it to go higher by a centimeter or so. Any advice before I start stripping the chrome off the nuts? http://www.angel.cc/img/sprint1.jpg
February 15, 200719 yr This looks like a conventional headstock Zammo. The large nut is the headstock bearing adjustment lock nut, there's a pair against each other, the lower one tightens the bearings, the upper locks it. It's the allen bolt at the top which adjusts the handlebar stem height. Using the right allen key, slacken this and it takes pressure off the cone in the bottom of the stem tube that clamps the stem. Then twist the handlebars from side to side, working them up that centimetre. Finally align the handlebars and tighten the allen bolt again. If it's almost impossible to twist it up, give the top of that allen bolt a sharp tap to free the tapered cone in the bottom of the stem tube. . Edited February 15, 200719 yr by flecc
