Feedback Sports FATT RAKK
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.
