Freewheel ThreadingĪll recent freewheels and threaded hubs, regardless of where made, use ISO threading. The bearings center the outer body on the inner body, and allow the inner and outer body to turn freely relative to each other when the cyclist is coasting. The front (right) side of the freewheel has another bearing assembly, not shown in these photos. In the previous photo, part of the inner body's bearing race is visible as a polished arc (blue arrow). The bearing balls roll between this bearing race and one on the inner body. The photo also shows bearing balls in a bearing race, embedded in grease to hold them in place during assembly (also a few bearing balls that got away). This particular freewheel has two pawls directly opposite one another and an odd number of ratchet teeth, 15, so only one pawl engages at a time. When the cyclist is pedaling, the outer body also turns (counterclockwise in the photo), the pawls engage the ratchet teeth and the freewheel is silent. The freewheel makes a characteristic tick-tick-tick sound as the pawls spring into place behind ratchet teeth. When the cyclist coasts, the pawls slip forward (counterclockwise in the photo) over the rachet. The ratchet is the circular stepwise arrangement near the center of the photo. The photo below shows the outer body from the back (left) side. Small wire springs, visible in the photo, rotate the pawls outward. The red arrow points to one of the two pawls of this freewheel. The outer body (the part that holds the sprockets) has been removed. The photo below shows the inner body (the part that threads onto the hub) of a freewheel. Most freewheels achieve this by means of pawls which engage a ratchet. Check out our collection of BMX Wheel Parts and BMX Hubs.The outer body of a freewheel can turn freely in one direction relative to the inner body, but not in the other direction. But when that time comes, we offer a great range of parts to keep you riding. Protecting your hub and spokes with a hub guard means that you won’t have to replace other bike parts as often. No matter which type you choose, grind with a guard rather than without, as it is going to offer a smoother ride. On the other hand, the aluminum hub guard is more durable. A nylon hub guard will provide an easier grind than its aluminum sidekick. They are available in both front and rear versions.īMX hub guards come in many materials, but the two most common are nylon and aluminum. As you can imagine, these guards will work with the majority of set-ups and do not need to be brand-specific. You will find that some brands offer universal hub guards.
#Falcon bmx hub driver
Every drive side guard has a cut-out section that allows the chain to move around the driver without catching. There is also a difference between drive side hub guards and non drive side hub guards. Front hub guards are compatible with a 10 mm axle, and rear hub guards will take a 14 mm axle. When choosing a hub guard, it is important to know which kind you are looking for. They can also reduce friction, making your grinds smoother and longer. As riders grind on rails and ledges, the hub guards act as a shield protecting the wheel. They are a cone-shaped cap that sits on the outside of the front or rear hub at the center of the wheel. To avoid damaging your BMX hubs and spokes, hub guards are a great idea.
