What this tool does Accurately measures and corrects spoke tension on bike wheels so you can maintain wheel strength, ride quality, and safety. Designed specifically for mountain bike rim wheel groups to help you keep spokes evenly tensioned. Key benefits — why you need it Prevents uneven tension that leads to wobbles, premature spoke breakage, and compromised handling. Helps you make precise adjustments quickly using a built-in voltage comparison chart for reference. Built from durable aluminum alloy for long-lasting performance and reliable on-bike service. Important attributes Function: multi-tool for measuring and correcting spoke tension. Compatibility: suited for mountain bike rim wheel groups. Material: robust aluminum alloy construction for durability and consistent measurements. Performance: provides repeatable, accurate tension checks and a clear chart to guide adjustments. How it stands out Combines measurement and correction in one handheld tool so you can evaluate tension and act immediately. The included voltage comparison chart removes guesswork and speeds up precise tuning. Practical use scenarios Pre-ride inspection: check and correct spoke tension before a long trail ride to reduce the risk of mechanical issues on remote sections. Post-impact repair: after a crash or hitting a rock, quickly assess affected spokes and make targeted corrections to restore wheel stability. Wheel building and maintenance: use during wheel truing or routine shop maintenance to ensure uniform tension across the rim. Quick usage tips Use the tool to read each spoke’s tension, compare the reading to the voltage comparison chart, then adjust spokes as needed for balanced tension. Recheck neighboring spokes after adjustments to confirm even distribution. This tool gives you a practical, long-lasting way to keep your mountain bike wheels correctly tensioned, combining accurate measurement, on-the-spot correction, and a convenient reference chart.
