UCRS frame walls mount to the 5050 Core 2.0 aluminum frame system. The Core, wheels and any skates pictured are not included with purchase. The UCRS 60-55 is designed to ride 55mm wheels on the inside and 60mm wheels on the outside for a flat ride or 56mm wheels on the inside for a slight 0.5mm rocker with excellent wheel bite protection and a groove that requires no break in. Other wheel size combinations may be possible.  UCRS frame walls and H-blocks are 3D printed on demand in PLA + filament. They feature a dovetailed H-block that can be replaced or printed in other materials by yourself or 3rd party printers such as Shapeways. H-block 3D files are free to download. If you selected custom colors, please remember to choose colors available in Esun PLA + filament and write the colors in your order form. UCRS is a one man and one 3D printer operation and 3D printing is a slow process. Depending on order volume and availability of custom colors, expect up to 3 weeks from your order being placed before it will be shipped.  Purchases can be made in Monero, Zcash, Bitcoin, or credit card. Shipping discount for all purchases with cryptocurrency. List of ESUN PLA+ colors
