The Odyssey Aerospace features an “aero”, or “V-shaped” cross-section, which creates a unique structural design. Made from 6000 series aluminum this rim is incredibly strong and durable while being light and affordable. Thick inner sidewalls, and a lowered center wall section provide more room when installing or removing tires, and running brakes isn’t an issue. The Aerospace uses a traditional lacing pattern, just like the Hazard Lite, Seven K-A and Quadrant. ###section### Product Specs WHEEL SIZE: 20\" SEAM: Welded ERD: 380mm HEIGHT: 23mm WIDTH: 34mm SPOKE HOLES: 36h WEIGHT: 450g / 15.9oz
