BOB NUTZ work in place of the BOB Quick Release on bicycles with solid rear axles. BOB Nutz are available in four different sizes to fit a variety of sizes of solid rear axles.
Be sure to determine the correct size for your bicycle’s solid rear axle. The size of your rear axle can generally be determined by looking it up in reference to the manufacturer of the rear hub.
If you can not determine the size of the rear axle through the hub manufacturer’s brochure or online information you can determine axle size by removing one of the nuts. Take the nut into a hardware store or local bike shop. Determine its size by checking which size axle (or bolt) it will thread onto.
