How do I choose an MTB wheel?
There are many different sizes of MTB wheels and it is important to get the right one to fit your bike. There are five things that you need to consider when choosing a new wheel; wheel diameter, axle type, hub spacing, rim width and freehub type (rear wheel only).
What are the different wheel diameters (sizes)?
MTB wheels are available in 4 different diameters:
What are the different axle types?
There are different axle types for front and rear wheels:
What about hub spacing?
As with axle types there are specific hub spacing’s for front and rear wheels:
Why does rim width matter?
Yes. This is because weight on the rim adversely affects acceleration and climbing more than weight on any other part of the bike. Having said that a wider (and heavier) rim is more robust and will offer more support for the tyre. For this reason, cross country MTBs tend to have narrower rims than trail and downhill bikes. As long as you get the wheel diameter, axle type and hub spacing to match your existing wheel it is usually possible to change the rim width for either a lighter or a sturdier wheel.
What about Plus sizes?
Plus sized 27.5” & 29” wheels use very wide rims (38-50mm) that require Boost standard hub spacing. You can only use these rims on ‘Plus Sized’ bikes.
What are the different freehub options?
The freehub is the part of the rear wheel that the cassette fixes on to. There are 3 main freehub types that fit specific cassettes:
If you match the above criteria, then you can be sure that the wheel you buy will be compatible with your mountain bike.
Do I need a disc specific wheel?
If you have disc brakes on your bike then you will need a disc specific wheel. There are two different types of disc rotors that are compatible with different hubs:
Note – disc specific wheels are not compatible with rim brakes.
What about tubeless?
Some wheels are ready to be used with tubeless tyres straight out of the box while others can be converted with a simple conversion kit. This will usually be specified in the product description.
