Zipp 404 tubeless wheels are only compatible with certain bike frames and forks. To determine if your bike is compatible, you need to know the width of your bike's rear axle and the size of your bike's tires. The Zipp 404 tubeless wheels have a width of 21mm and can accommodate tires with a width of 25mm or wider. If your bike has a rear axle width of 12mm and tires with a width of 23mm or less, then it is not compatible with Zipp 404 tubeless wheels.
