Can I raise the handlebars on my Marin hybrid bike and how do I do it?

Most likely you have a threadless headset on your Marin which means you can not raise the handlebars without replacing the stem or handlebars themselves. In addition, many times you will also have to replace some of the cables and housing because they will be too short once the handlesbars are raised.

If you do not have a treadless headset than raising your handlebars is very simple. First check to see what type of headset you have. A threadless system with have a allen head on the very top of the stem and one or two more allen head bolts on the side of the stem. The threaded system will usually have only one bolt on the very top of the stem. It is sometimes covered by some type of cap. Also on threaded headsets, there will be a large nut under the stem, which is what most people mistakenly loosen to adjust the stem. Do not touch this nut, it will adjust the headset. Same goes for the allen head on the treadless headset, it will also adjust the headset so don't touch it.
So if you have a threaded stem, simply loosen the allen head or nut on the top of the stem and raise the stem up. Make sure you do not go above the max line and that you are still able to turn the handlebars freely.
