Maintaining your Spokes

To check for and tighten loose spokes, go around the wheel squeezing pairs of spokes together

with your fingers.

• If a spoke gives when you pull it gently, it needs to be tightened. Tighten loose spokes at the

nipple, where they meet the wheel rim, with a spoke wrench, turning each one a little bit at a

time.

• If a spoke does not give at all, it may be too tight. Loosen it by turning the spoke nipple the

opposite direction.

Another method for checking for loose spokes is to pluck each spoke with your fingernails. If a

spoke makes a sound noticeably lower in pitch than the other spokes, it should be tightened. If a

spoke makes a sound much higher in pitch than the other spokes, it may be too tight and should be

loosened.

To check the wheel’s alignment, lift the wheel off the ground and spin it while you look across it

from one edge. Your wheel should turn freely and smoothly with no wobble. You can also use a

stationary object (like your frame) to see if the wheel stays the same distance away while spinning.

If the rim is bending or wobbling to one side of the wheel, tighten spokes on the other side of the

bent part of the rim to center the rim. A bicycle mechanic will be able to do this if you need help.

To make sure your rear axle is tight, push sideways on the wheel rim. The wheel should not wobble

around the axle. The wheels should not touch the back tubes or rub against your clothes. Tighten the

nut(s) on your rear axle to eliminate the wobble. Make sure the wheel rotates easily; if the wheel

does not rotate easily the nut is too tight.

You may be able to check the wheel’s alignment while seated in your

chair by taking your weight off the wheel and suspending your wheel

in air while spinning it.

Spokes

Loose or broken spokes can cause a wheel rim to bend. A few loose spokes will not necessarily

make riding more difficult; however, they may allow a wheel to collapse when going over a curb

or a big bump and can also make other spokes break more easily since there will be more tension

on them.
