I think that I need to raise the bars on my bike.. I have the ritchey logic threadless headset. Can they be raised and if so how much, the stem will need to be raised the bars are straight..
Thanks

Are there spacers? If so, are they above or below the stem? Is the stem level or angled? If angled, does it point up or down? Do you have any other stems? Much more information needed.

How high do you want to raise them?

1. Look at your stem from the side. If it looks like it's pointing down you can probably raise your handlebars about 1" by flipping it over.

2. To raise your handlebars about 2" you can replace your stem with one that has a steeper rise angle. Be sure to think through the geometry because raising the handlebar will also bring it closer to your saddle.

3. If you want to raise your handlebar by 3" you'll probably need to buy a stem riser.

Raising your handlebars by 2 or 3 inches may make it necessary to buy new cables and housings.

The short answer is usually "no" without buying parts, as most stock bicycles are sold with the stem pointed up and already at the top of the steerer tube.

Retro Grouch's post covers it thoroughly.
