The style of your freehub body relies upon the kind of drivetrain and cassette you have. The common mountain bike axle standards are: Name A wider axle implies that the flanges on either side of the hub can be placed even further to improve the bracing angle and eventually the strength of the wheel. As and when the newer ones are launched, they automatically gain all of the attention. The ones that are designed keeping in mind gravity riding might be made using steel so that your bike stays well-balanced.Īxle standards are pretty much like technology, they are subject to constant change. Majority of bike hubs for MTB are made using some kind of alloy, majorly carbon fibre as it is pretty light weight. Also, they are even cheaper as compared to the cup and cone angular bearings. However, servicing them can be a bit tricky. They are a great pick when lubricated regularly and are cheap to maintain.Īlso, the load is distributed in an even manner and these bearings can handle radial (up and down) and axial (side) loads in a much easier manner.Ĭartridge bearings are packed into a single sealed unit, which implies that they are much easier to replace and do not need any adjustments. As and when the wheel spins, the balls move freely. The cup and cone angular bearings use loose ball bearings that are in a cup within the hub and are held together by a cone. Your hub will either come with a cup and cone angular contact bearing or a sealer cartridge bearing. Hence, you must keep a couple of things in your mind to pick the best one for you. Now that you know that a bike hub is imperative for your mountain bike, picking the best one can be a bit of a task. What should you look for while buying a hub for mountain bikes? The cassette/ sprocket that drives the rear wheel is appended to the rear hub which lets you to freewheel. The front hub of the bike is meant to let the wheel to spin while the rear hub is responsible for the bike’s transmission. A bike hub is the central part of your MTB’s wheel, both front and rear and it helps the wheel to spin freely as it connects to the bike’s wheels’ rim through the spokes where the axle is fitted.
