One way to store your fatty is to deflate the tires and balance it on its own the rims. It'll work, but we definitely don't recommend it. A better way is with Feedback Sports FATT RAKK. It's optimized for 3 - 5-inch-wide bicycle tires and the cones can be adjusted for the best fit. Like the regular RAKKs, the FAT uses a spring mounted arm to hold the front or back wheels. It doesn’t touch the spokes, rim, or rear derailleur and the modular design plays nicely with your other RAKKs.
