I'm a complete noob at biking so I'm learning as I go. Long story short, my gf and I moved to wexford, pa and everything we need is within a mile or two. We have two off roading jeeps that hog gas so I picked up two cheap bikes on CL to get us around. They will be our "starter" bikes until we build up funds to get the more $$ fancier bikes. One is a Magna XL2 26" mountain bike and I believe it's a 21 speed. It's in good shape but not perfect. I believe the front wheel bearing is gone cuz I can wobble the wheel a little side to side. I've done a little searching on google but cannot come up with the type or size of bearing in this wheel. It has a disconnect knob to remove the wheel if that means anything. Can anyone help, or at least point me in the way of finding out what bearing is in there?
I'm a do-it-myself-er and I fix everything that I can and would like to tackle this job myself.
