HIGH-QUALITY MATERIAL - The pedals are equipped with a pair of adjustable elastic straps that allow you to adjust the fit to your shoes. The high-quality strap is easy to use on the pedals, and the pedals and straps are placed in the correct position before use to ensure the perfect combination of shoes and pedals. PEDAL SPECIFICATIONS - Our pedals have a 9/16 inch spindle (spindle diameter is 14.3 mm). Suitable for all 9/16 spindle bikes including indoor bikes and spinning bikes. Pedal size: 14 cm long, 12 cm wide, shoulder strap size: 32 cm long. EASY INSTALLATION - The pedals are clearly marked left and right, and the markings are checked before replacing the pedals for correct installation. The bike pedal is a 9/16 \" spindle. Check your bike spindle needs and choose the correct size. EXCELLENT CONTROL - The pedal surface is non-slip and has a strap on the top to ensure a good connection to the shoes. This prevents the shoes and pedals from suddenly slipping, allowing you to keep them stable when pedaling.
