MH019 Mountain bike hub 135mm

The bicycle hubs, as a crucial component in mountain bikes, not only carry the function of connecting the wheel to the frame, but also determine the performance and riding experience of the whole bike to a certain extent.
Firstly, structurally speaking, the hub contains bearings that are connected to the rim through the spokes, and together they form a complete wheel set. It is a precise and complex design that ensures sufficient strength to support the weight of the rider and the vehicle, as well as smooth rotation to minimize drag.
Hubs come in a variety of materials and types, with iron, chrome steel, aluminium alloy and carbon tube hubs dominating the mainstream market, while titanium alloy hubs are difficult to make due to the production process. According to the ratchet part of the hub can also be divided into cassette hubs and rotary hubs. Cassette hubs with flywheel for the card type, the hub has no thread, only the ratchet ; while the rotary hubs are with teeth thread, the flywheel is spinning up. In the current market, cassette hubs dominate due to their more stable performance and wide compatibility.
