The Shadow Optimized freecoaster is much more than the next step in Shadow hub design. The performance, value, & strength of the Optimized freecoaster is the materialization of modern day BMX riding through the eyes of the br&. The Non-Drive side of the Optimized freecoaster was designed completely around grinding. Included is a completely integrated non-drive side plastic hub guard that easily slides over the existing cone to simpifly your installation experience. They’ve designed a smaller hub flange to stay out of the way which allowed them to create a smaller hub guard that doesn’t need to be gigantic to get the job done. On the inside, they’ve moved to a more reliable bushing resistance system that dissolves all previous engagement issues. Creating a more enjoyable freecoaster experience for you. section Product Specs HUB TYPE: Freecoaster AXLE: 14mm Male DRIVER: 9t SPOKE HOLES: 36h WEIGHT: 733g / 25.85oz
