CHOOSE YOUR HUBS
A good quality, sealed bearings hubset should last you a lifetime if properly looked after and serviced. To choose the correct hubs for your bike, first we will need to know the dimensions of your fork and frame dropouts - the width in which the hub sits in the dropouts. The most sure fire way to find this out is to take your wheels out and measure the space in between. Sometimes shop listings of bikes on websites, and even manufacturers websites don't provide accurate enough specifications.
We will also need to know how the hub axle is attached. For example, this could be quick release skewers or thru axles.
The type of driver or freehub is also a piece of information we need to know. This is the part of the rear hub the cassette fixes onto. Common driver types include Shimano HG, Shimano Microspline, SRAM XD or SRAM XDR.
