What should I do if the SRAM self-extracting cap fell off my bike?

If the SRAM self-extracting cap fell off your bike, you should immediately stop riding the bike and contact a professional bike mechanic for assistance. Attempting to ride the bike without the self-extracting cap can cause damage to the crankset and potentially lead to safety hazards. It is important to have the cap properly reinstalled by a trained professional to ensure the bike functions correctly and safely.
