I'm looking to get a separate wheel for my indoor trainer for easy swapping between indoor and outdoor. I found a used wheel + cassette that has a SRAM 10 speed cassette on it already. Will this work with my setup? Would it be easier to just replace the cassette on the trainer wheel?

If you had 9 speed on both the wheel and trainer, or both 10 speed, then it would likely work fine.

However you have once of each, and that won't work well together. There may be one or two cogs on the 10 speed cassette that line up with a 9 speed position on the rear derailleur.

Your best option is to buy another 9 speed cassette and keep the whole lot 9 speed.

    Thank you! I found a 9 speed cassette instead so looks like I should be good.
