Not only are you slower (even if your rim isn't rubbing against the brakes, its out-of-round profile causes more drag and friction), but the ride is rougher, you have less control, and you could end up on the ground if the wheel folds or a spoke breaks thanks to the pressure of uneven spoke tension. If you suspect your wheel is wobbling, don't hesitate. The earlier you catch a small bend, the easier it will be to fix. A truing stand is the most accurate tool for the job, but you can get by using the brake pads on your caliper-brake bike. Follow these four simple steps to straighten your wheel and stop getting dragged down.<BR><B>1. Even Out Tension</B><BR>lace the offending wheel, tire off, in a truing stand (or remount it in your bike's drops). Then, before you begin truing, check spoke tension by wiggling each spoke. Use a spoke wrench to tighten spokes that feel loose relative to the others--just so they're about as snug as the two spokes closest to them; don't crank down. If a spoke feels tighter than the others, pluck it. If it sounds shriller than its neighbors, loosen it until the tones match. Caution: On rear wheels, because the hub is offset by the gear cluster, spokes on the right side of the wheel are tighter than those on the left side.

Using the gauge on the stand (or the brake pads if you're truing on the bike), locate one spot on the rim that rubs. (For simplicity, work on only one spot at a time, even if there are multiple rubs.) To fix the rub, you need to pull the rim toward the opposite side. You accomplish this by tightening the one or two spokes that sit near the rub on the opposite side of the rim. Tighten them just a quarter-turn at a time. So, if the rim is warped to the left, tighten the right-side spokes. On the same side as the rub, find the spoke parallel to the one you tightened, and loosen it an equal amount. (This maintains equal tension radially, or up and down, so you don't create a hop.) Spin the wheel and check for a rub in that same spot.

If the rim has a high spot, it will have a corresponding low spot directly across the diameter of the wheel. To remove the hop, loosen the spokes a quarter-turn at the low spot; and snug them a quarter-turn on the high spot.
