High-grip tires for Hang-On Racer size Wheel spacers for GRP GR60 tires Made with a 3D printer. What you will receive are four 1/2 circle parts (excluding the wheels) as shown in the first photo. Although these tires have higher grip than ZH tires, GRP tires are not widely distributed in Japan and are rarely seen. The inner diameter of the tires is larger than the outer diameter of the HOR's stock wheels, making it difficult to create a perfect circle if you force them to be glued on. Therefore, I created spacers to "cover the wheels and fill the gap with the tires." If you have GRP tires or can buy them, please give them a try. To install, glue the 1/2 circle parts together, rotating them 90 degrees and flipping them over. Then, glue the GRP tires on top. The weight when attached to the wheels is "66g" (see photo 4). Shipping will be via "regular mail" (Japan Post). Instant purchase is OK without questions. By the way, I am the aforementioned "Chevron Models." I create these using a 3D printer (with 0.1mm layer thickness for precision) and assemble and finish them by hand, so I can't make many. Therefore, they cannot be distributed through wholesalers or retailers like our other products. (The price is set to exclude the markup for direct sales.) Thank you for your understanding. Thank you.
