Set of four Apex Series, New Street Style All Terrain Polymer (ATP) fingerboard wheels in "Pitch Black". These superior performance, highly durable custom off-road polymer wheels are brand new to the fingerboard industry and exclusive to Teak Tuning. The Apex Series ATP wheels feature a low friction grip for a soft and smooth feel while riding. Teaks custom hybrid polymer blend picks up less dirt and provides excellent control and performance on any surface, smooth or rough, indoors and out. These wheels have a low-level squeal when you slide across a surface or make a sharp turn. Despite the softer 65D durometer, the polymer blend material is extremely durable and resistant to damage. Measuring 7.9mm in diameter and 4.9mm wide, these wheels are ideal for all skill levels and for pulling tricks on almost any surface. These wheels contain high quality bearings with an ABEC-9 rating. These bearings are our highest quality fingerboard wheel bearings. They are extremely smooth and completely silent. These are heavy duty bearings that will allow for extreme movement and control. However, because they are greased and fully shielded, they do not have the free spin that our "Ultra Spin" bearings do. In actual use, they are extremely responsive and have a very free roll. These wheels are designed and manufactured in the USA with a high quality hard plastic material, custom teak blend. Each wheel is cast and cut in New York. Colors are mixed by hand and may vary slightly between sets. Perfect for riders of all skill levels. Includes a teak tuning sticker. Choking hazard: small parts. Teak Tuning products are designed and manufactured for teens and adults alike. Products contain small parts and are not safe to put in the mouth due to materials and choking hazards. Keep all Teak Tuning products out of the reach of children 14 years of age and younger.
