I now have two Shimano 9-speed cassettes. The one that came with the bike and the one that came with the Zwift Hub.
I’m wondering if I can just take the back-wheel off of my bike and attach my bike to the Zwift Hub using the 9-speed cassette that came with the Zwift Hub? Will I have to do any alignments/adjustments or are both cassettes virtually the exact same as they are both Shimano and both 9-speed?
New to cycling, excuse me if this is an obvious answer.
The spacing is different between the gears only if you have a different number of gears eg. 10spd or 11 spd. It’ll work even if you have a different number of teeth, the derailleur will accommodate that difference within reason. Enjoy your ride!
