Troubleshooting
Brakes feel weak or are noisy
Check brake pad alignment and wear. Ensure the brake cable is properly tensioned. For persistent issues, consider a professional brake adjustment or explore upgrading to hydraulic disc brakes if compatible.
Gears are skipping or not shifting smoothly
Inspect the derailleur for bends or damage. Check shifter cable tension and ensure it's clean and lubricated. A tune-up by a bicycle mechanic may be necessary to realign the derailleurs.
Bike makes rattling noises
Check that all bolts are tightened, especially those for accessories, stem, handlebars, and seatpost. Inspect the headset for play.
Tires go flat frequently
Ensure tires are inflated to the recommended pressure. Inspect tires for embedded debris or wear, and consider using tire liners or upgrading to more puncture-resistant tires.
