    Clarification.............what is the "stem"?

    749px-Adjustable_threadless_stem._1JPG.jpgOn the attached photo there is a green line and a pink line. Which one is the "stem" and which one is the "steerer"?

    Second question; can I get a replacement for the green one that is longer and therefore allows me install it vertically to raise the height of the bars? (rather than use an extender that requires me to remove the clamp on the top of the forks).

    The stem is represented by the gree line in your pic.

    Stems come in many shapes and sizes, you should be able to find on that is longer and angles up. your current stem looks like it can be angled up but using the bolt just ahead of where it attaches to the forks steerer tube, repersented by the red line. You will have to loosen the clam around the bars to adjust the angle of them as the stem angle increases.

    Yes; thanks, I actually have mine adjusted closer to vertical (the picture is just a random off the internet).

    So what's the "steerer" then - is it the top tube of the forks?

    Not meaning to offend but what the *%^$ have you been doing in your 4 years 797 post time at BF?
    If you have to force it... you probably shouldn't.

    Raise the bars too much and you will need new cables and housings for your shifters and brakes.
    Bikes use brakes to stop.

    If your bike has breaks, don't ride it.

    I was sort of wondering the same thing.

    009jim, For a threadless headset system there is only a stem to attach to the handlebars and clamps to the outside of the steerer tube. With a threaded system there is the quill which is what is inserted into the steerer tube while the stem attaches to the handlebars. A threaded to threadless adaptor only has a quill.

    The "steerer" is the top portion of the fork. You have 2 fork blades, connected at the "crown". Then inside the frame, the steerer tube extends up from the crown and comes out the top, where your stem is attached.
