Parts that wear out during normal use are not covered under warranty.

These components include, but are not limited to: chain, rims, spokes, brake pads, inner tubes, outer tires, brake discs, grips, hubs, rubber moving parts, derailleurs, brake cables and conduits, stripped threads/bolts, drive gears, saddle, and tools.
