How do you raise the handlebars of a trek 6000?
I have moved several times and have lost the owners manual. I have tried the bolt that goes down the stem, but it does not budge.
depends on what kind of stem you have: threaded (older) or threadless (newer). it's a threaded headset, then a tap on that top bolt should loosen the stem's internal locking wedge. classic way of loosening is to take a wood board or at least a cloth, place it over the bolt, and tap with a hammer. a threaded stem doesn't have threadless clamping bolts on the end closest to the rider. raise your stem, align, and then retighten.
if you have a threadless headset (meaning the stem clamps onto the top of the fork with bolts), then loosening that top bolt won't do anything. you have to loosen those stem bolts (not the ones at the handlebar end!) as well as the top bolt. BUT!!! you can't raise the stem any higher than your existing stem + spacers stack height, so unless the builder left a spacer or two on TOP of the stem that you can move under the stem for just such flexiblity, you're stuck. The only option is to buy a "riser"stem that angles up instead of perfectly flat.I don't know about a the trek 6000, but the handlebar height on most bikes is determined by the stack height. You would have to insert spacers between the stem and the headset, but only up to the amount of space available (it depends on how short they cut your fork). The bolt you are referring to probably is the one that removes the stem from the headset.
It looks like the Trek 6000 has a threadless type stem and headset. In order to raise the handlebar you will have to either get a stem that angles up more towards the rider, or get a "riser" type handlebar. Any good bike shop can help you with either option. Have fun!
I think that most likely you would need a new stem that has a larger angle, or a new handlebar with higher rise. It depends on what setup you currently have.
The idea on the spacers under the stem might work, but it would depend also on how long the steerer tube is cut. If it is cut without any spacers on top of it, I don't think you should rise the stem that way.
Go to a bike shop so they can help you with that (suggest different stems/handlebars) and they can install it properly.
