Set of four short fingerboard wheels from the Apex series, in "grey and white". "Short" shape mini wheels are slightly smaller than your average fingerboard wheel. These small and compact wheels are ideal for maximum control and tricks on all types of surfaces. Shorty 61D wheels are our softest wheels to date, and are equivalent to a hardness of 101A. The feel of these wheels is very similar to real skateboard wheels. They are not too hard and they are not too soft. Measuring 6.6mm in diameter and 5mm wide, these wheels are ideal for easy riding and pulling off a variety of tricks. Many skaters love the squeal that urethane wheels make as they glide across a surface or take a sharp turn. Shorty Apex wheels contain premium 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. Each of the gray and white swirl wheels features a unique variety of black, gray, and white colors. These wheels are designed and manufactured in the USA with a high quality custom teak urethane 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.
