Troubleshooting wheels

 

 

Symptom Cause Solution
Bike feels slow, you feel tired after short rides Cones too tight on front or rear wheels, or both Adjust cones so that wheels spin smoothly
Bike feels uncertain when cornering Cones too loose – wheel will wobble from side to side on the frame Adjust cone so that the wheel can’t rock from side to side in the frame
Wheel is buckled True wheel so that rim runs true and doesn’t wobble from side to side as the wheel spins
Insufficient tyre pressure Inflate tyre to minimum pressure marked on the sidewall of the tyre
Rim brakes – rim rubs on V- or cantilever brake blocks Wheel is buckled True wheel, so that rim runs true and doesn’t wobble from side to side as the wheel spins
Brake blocks wear quickly Rims dirty Clean rims with degreaser
Rims worn Check rims for scours, grooves or ridges – replace rims or wheels
Spokes loosen repeatedly Rim buckled Uneven spoke tension in buckled wheels causes spokes to loosen – rebuild wheel with new rim
Frequent punctures Tyre still has sharp things stuck in it Check tyre carefully, feeling around the inside for protruding thorns or glass – fold the tyre inside out, so that you can see more clearly
Spokes poking through the rim Run your fingers around the inside of the rim, checking for sharp spoke ends – file sharp ends off
Rim tape shifting, exposing spoke holes Replace rim tape with wider, tighter one
UST tyres leak Tyres need pumping before every ride This is normal! Fit tubes for normal riding, take them out again on race days – an unexpected training bonus!
