Installation Notes Remove wheel from bike and disassemble axle by unthreading existing bolts. Clean dropout and axle threads to remove dirt and debris. Install new bolts hand-tight, then tighten in alternating sequence (left-right-left-right) to ensure even clamping pressure and prevent wheel binding. Final tightness should be snug but not excessive—over-tightening can strip threads or crack dropout.

Maintenance Tip Check bolt tightness regularly before riding, especially after extended riding sessions or after any impact. Loose bolts can cause wheel movement and compromised handling. Replace bolts if threads become stripped, caps become damaged, or if bolts loosen repeatedly despite proper tightening.

Performance Note Properly tightened bolts ensure consistent wheel alignment and eliminate lateral play that can affect steering precision and overall bike control. Tight, secure bolts are critical for race performance and safe operation.
