Confirm model Please make sure to remove the old bearing, and verify its exact model by checking the laser-etched information or precisely measure the inner diameter, outer diameter, and width. Core advantage Full Ball Structure & High Precision: Adopts full ball bearing design, with higher load-bearing capacity and smoother rotation compared to ordinary bearings. The precision reaches ABEC-3 level, which effectively reduces friction during operation, avoids abnormal noise of bicycle frame, and improves riding comfort. Durable Material Selection:The inner and outer rings as well as the balls are made of bearing steel GCR15which has strong wear resistance, corrosion resistance and impact resistance. It can adapt to various complex riding environments such as road, mountain and daily commuting. 4PC Standard Packaging: Each model is packaged in 4 pieces per set, which meets the replacement needs of most bicycle frame bearing positions (one bicycle frame usually needs 2-4 bearings).
