Review on 🔧 BASEEING Bike Spoke Wrench Tool 8 Way Hard Steel Bicycle Rim Truing Tool for Adjusting Bicycle Wheel Tension 6 Sizes in 1 Cycling Pocket Spoke Tools for Bike Repair and Adjustment - Set of 2 by Kevin Schnitzer

So if you're buying a bike from one of those big discount stores, PLEASE look at the wheels and make sure they're straight? Just hold the bike up and around, look at it from the edge and see if everything is straight. If not, you need one of these. Fixing a bike can be expensive. But it's easy. If you are using this tool and need to adjust the wheel, turn the spokes counterclockwise to loosen them on the side you are moving away from, then tighten the same number of next spokes on the other side . the same speed (otherwise you might get a wheel out of a round one). DO NOT do more than 1 or 2 turns at a time, it makes a big difference. If your tire is mostly straight but you have a crooked section, you can put painter's tape on the tire where that section begins and ends to help you adjust the exact area you need. Small steps. SMALL.
