Common failures
A chain that derails, a sprocket with hooked teeth, or a loose front or rear sprocket bolt can stop the ride or damage nearby parts.
Trail readiness / drivetrain reliability
The common trail drivetrain failures are chain derailment, damaged master links, loose sprocket hardware, worn teeth, poor slack, and chain guide damage. The right response is to stop early, inspect, and recover the bike instead of forcing it to keep running.
A chain that derails, a sprocket with hooked teeth, or a loose front or rear sprocket bolt can stop the ride or damage nearby parts.
Stop the bike, check the chain path, inspect the master link and bolts, and decide whether the bike can safely move under its own power.
Do not keep riding with a visibly damaged chain, a missing fastener, or a sprocket that no longer holds the chain properly.
Contact the team if the failure looks connected to a fitment issue, a conversion, or a sprocket wear pattern that repeats too early.
