Bike dropouts are an essential part of your bike, and are located where your wheels attach to your frame. Bike dropouts allow for your bike wheels to be removed and replaced without having to remove your chain or derailleur. Although technically classed as a bike component, bike dropouts are actually an integral part of your bike’s build, as they let you easily and efficiently remove and replace your bike wheels without hassle. At Dolan, we stock a variety of bike dropouts to cover our catalogue of bike frames old and new. Check out the full range below!
