I'm trying to buy a new wheel for my mountain bike and I went online and was lost in the different specs of the wheels.

I currently have a 1×9 on the bike. I don't know anything else about the cassette or wheel because I bought the bike used.

I plan on getting a new groupset as well, do I need to buy both the wheel and set at the same time?

    We need more details (e.g. if the frame runs disc brakes, wheel size, if it uses a thru axle, and what kind of upgrades you intend to make).

  • There are a large number of standards of axles types and hubs these days. sheldonbrown.com/frame-spacing.html helps with spacing (although I don't think this is complete now), then you have QR or through axle options.

    You probably should head down to a local shop and see what they've got/can get. Note that many wheels you buy online might need a bit of truing when they come out of the box, which by the sound of things you're going to need a shop to do.

    By the time you pop for a rim/hub/spokes and cassette/shifter/chain/cables and maybe a derailleur, you could be better off replacing the whole bike. Bikes by parts are funny expensive like that.

To answer the other part of your question, No you can upgrade the groupset later.

Assuming you buy a wheel with an 11 speed hub, then your existing 9 speed cassette should fit it, and an 11 speed cassette is the same width but with thinner chain. You'll need a new chain of course, and a right-hand shifter that has 11 positions not 9.

You should be able to use the front chainring as-is, subject to wear.

I can't say whether you will need a new rear derailleur or not - you should get away with the current one, but its not guaranteed.

New shift cable and housing too because why not?


Since you've mentioned Tubeless in a comment, probably best to add new tyres and sealant. Add a spare tube to your pack as well, for bad punctures. If your front wheel is not tubeless compatible, you're up for a new wheel there too unless you only want tubeless on the rear.
