Below you will find options to connect your BOB Trailer to most common bicycle rear axles.
BOB Quick Release: Quick release (QR) rear axles have been around for decades and are commonly found on older bikes. Visit the QR product pages for a fit guide if you do not know your bike's rear drop out dimensions, which will determine the quick release length required. A QR is also used to attach the trailer wheel on all BOB trailers.
Thru-Axles: Almost all modern mountain bikes and many road bikes are equipped with thru-axles. These are larger diameter axles designed to add rigidity and strength. Visit the Robert Axle Project Thru-Axles product page below for more info and a fit guide.
BOB Nutz: If you have a solid rear bike axle this is what you need. Options are for different bolt diameter and thread pitch. Instructions can be found on product pages.
