How to Tighten Bicycle Spokes and True the Wheel Main Points:  Don't tighten spokes all the way the first time.  Take bulges and dents out of rim and make rim round before tightening spokes.  Easy to replace one or two spokes without taking wheel or tire off, except right rear.    All of this is dangerous.  Warning:  Bending a rim to straighten it as I describe can weaken the rim, and can cause it to break which could cause injury or death.  If you bend a rim, examine it after yu bend it to see if it has any cracks in it.  If it has a crack in it,  do not put it on a bicycle because it could be dangerous.  Also, spokes that have been under too much stress could break while someone is riding the bicycle causing a wreck, especially if more than one spoke breaks at the same time.

How to install Bearings and Cups in Bicycle one piece Crank

How to install Bearings and Cups in Bicycle one piece Crank Frequently, when a crank bearing tears up, the inside lip of the  cup has cracked and is bent.  This will cause new bearings to tear up soon after you put them in.  Sometimes, the inside lip of a cup has a crack in it and has not yet become bent.  You can probably see that crack by looking through the inside of the bottom bracket shell with a flashlight.  If the inside lip of a cup is cracked and  not bent, it might be several days, months, or years before it bends and causes the bearing to tear up.  Most bicycle mechanics advise to replace cracked cups.  If you want to remove the old cups, just get something long enough that you can hit with something to knock the cups out.   Don't hit the cup so hard  that it comes out the first time you hit it.  Instead, hit the cup a few times in different places until it comes out.  To put in new cups, get a flat piece of wood almost as wide
