Troubleshooting
Wireless shifting not responding or inconsistent
Ensure AXS batteries are charged. Re-pair the derailleur and shifter using the SRAM AXS app. Check for any firmware updates.
Brakes feel weak or noisy
Check brake pad wear and rotor cleanliness. Ensure hydraulic brake lines are not kinked. Bleed the brakes if necessary, following manufacturer guidelines.
Tires rubbing on the frame
This indicates that the installed tire width exceeds the frame's clearance. Install narrower tires, ensuring they do not exceed 50 mm (measured).
Squeaking or creaking noises
Identify the source of the noise. Common culprits include the bottom bracket, seatpost, headset, or pedals. Apply appropriate grease or tighten components as needed.
