The key to a strong and reliable wheel is properly and evenly pulled spokes, and the Zodazoqa tension meters correctly and reliably measures the tension of each spoke within the wheel, as well as the relative tension of all the spokes within the wheel. Zodazoqa tension meters are easy to use and affordable for everyone, and can be used effectively on bicycle spokes regardless of diameter, material and shape, not only for experienced mechanics, but also for manufacturing or correcting wheels, diagnosing wheel problems, or assembling new bicycles. The tension meter is made of 6061-T6 aluminum alloy material, manufactured by CNC process. The surface anodic hard oxidation treatment is durable, no deformation, corrosion resistance, and not easy to fade. It can be used for diagnosis, calibration, test measurement, repair and modification, including steel spokes, flat spokes, aluminum spokes, surface treatment for Mavic spokes, titanium spokes, etc. Suitable for mountain/road bikes. Tensiometer size (length and width): about 23*13.5*4cm/ 9. × 5.3 x 1.5 inches, suitable size, portable, convenient, anyone can use quickly, suitable for professional workers and daily use. Note: Due to differences in manual measurements, please allow for slight dimensional differences.
