This is a set of 8 inline skate wheels. Please inquire about the quantity. 【Highest Grade Bearings】 These are ILQ-11 bearings, which are equivalent to ABEC-11, two grades higher than genuine ABEC7. While ABEC is an industrial standard, ILQ is a standard for skate bearings. Although the quality varies greatly within the same standard, we have combined speed bearings that spin well and provide speed, selected by a shop owner who is a skater. 【Please Note】 As a skater pro shop, we adjust the parts before shipping and confirm that they spin well before shipping. Items that we determine do not spin well during pre-shipment inspection are returned to the manufacturer as defective products. You will notice the difference in smoothness if you spin them by hand before installation. There is a significant difference in quality compared to products that are acceptable even if they don't spin well. Please pay attention to quality to ensure that your precious children can play safely, securely, and enjoyably. 【Specifications】85A 【Size】110mm 【Bearings】ILQ-11 608 Includes high-speed bearings.
