Hello, just bought an Elite Zumo, downloaded Zwift etc - nearly ready to start except one thing - the cassette.
I was totally oblivious to the choices of cassette sizes and teeth until now, I’d love your feedback / assistance.
Q1. 9,10 or 11 speed?
Q2. 32, 34 or 36T?
Q3. Does it matter if I buy an entry level £20 or so, what would be the benefit of spending more money for the same brand? As I’m new to Zwift, I just want to get running rather than spend lots
Q4. What about my Rear derailleur on the bike? The cassette on my back wheel is 9-speed. If I added a 10 or 11 speed onto the smart trainer, wouldn’t I need to adjust the derailleur every time I wanted to use my bike as a normal bike?
Excuse my lack of knowledge - total newb.
I was close to buying the Shimano CS-HG81 10 Speed Cassette 11-36T but worried about buying the wrong thing.
