    As most of you know, I recently bought an 04 boulder se. I dug out an old mountain bike I had because my girlfriend was wanting something basic to ride around town with me. Unlike me, where I want to have something very reliable and study, she just wants to be able to coast at 15 mph and able to stay in shape a little bit, so when I told her she can have my old mountain bike she flipped out and was so excited.

    At first I kind of cringed, thinking well maybe it's best we get you something new. But I bought a 300 dollar bike when I'm going to do a lot of long distance and occasional trail biking, she'll probably ride about 3 or 4 times a week a couple miles around her area. So I figured a quick checkup on this mountain bike was necessary, and that if it passed my "inspection" it would suit fine.

    I redid the brake systems, they were a little dirty and needed new washers and new brake shoes. Now they work like a charm. I'm unsure of something else though. If I move the bike forward but continuously hit the front brake, the front end kind of jumps. I don't know the proper name, it's right below where the stem connects to the handlebars, but above the fork. Look at this picture.

    When I hit the front brakes, it's evident this piece is a little loose. It's not very loose, just a tad. It's one of those things that you know doesn't matter, but you want to fix it anyway "just because."

    Do I just have to tighten this up, or what? I didn't have the proper tools with me when I took the bike to my girlfriend's house and noticed it, so I figured I'd ask here before going over there to screw it up later this week.

    Wait wait so the steer tube of the fork actually has play in the headtube? If thats the case, I hope your familiar with headsets.

    Easy fix. Undo the bolts holding the stem to the steerer, just to loosen them, then tighten the top-cap bolt (the bolt on the top of the steerer). This, in turn, compresses the whole stem/spacer/steerer combo eliminating the play you're having. Re-tighten and align the stem and you're good to go.

    I came across a bike with that problem, it turned out whoever installed it has issues with compression rings

    The bike didn't always had this problem.

    I probably screwed it up somewhere along the way, heh.

    btw, thanks Trekkie.
